実験手順: To a suspension of 2,2,2-trichloro-1-{10-[(2′-methoxy-1,1′-biphenyl-4-yl)carbonyl]-10,11-dihydro-5H-pyrrolo[2,1-c][1,4]benzodiazepin-3-yl}ethanone of Example 1 (1.21 g, 2.25 mmole) in acetonitrile (25 mL) was added a solution of (2-amino-1-phenylethyl) dimethylamine (0.250 g, 1.52 mmole) in acetonitrile (5 mL), followed by dimethylsulfoxide (5 equivalents) and triethylamine (2.2 equivalents). The mixture was stirred at 82° C. under nitrogen for 18 hours. The solvent was evaporated, and the residue diluted with dichloromethane. The solution was washed with brine, dried over anhydrous magnesium sulfate and evaporated. The residue was flash chromatographed over silica gel Merck-60 using a gradient of 30 to 80% ethyl acetate in dichloromethane to provide the title compound as a light brown amorphous solid (0.777 g).

実験手順: As shown in reaction scheme 83, N,N-dimethyl-1-phenylethane-1,2-diamine represented by Formula 101 (439.1 mg, 2.67 mmol, purchased from Alfa Aesar Co.) and triethylamine (0.75 mL, 5.35 mmol) in THF (10 mL) solution were cooled to 0° C. under a nitrogen atmosphere, then, 3-(trifluoromethyl)benzoic acid chloride represented by Formula 153 (613.17 mg, 2.94 mmol, purchased from TCI Co.) in THF (15 mL) solution was slowly added thereto. After agitating the mixture at the same time for 30 minutes, the mixture was left at room temperature for 18 hours. A precipitate generated during the reaction was removed through filtration. The remaining solution was diluted with chloroform and this diluted solution was washed with a potassium carbonate (K2CO3) solution, followed by separation and drying the same with sodium sulfate (Na2SO4). The obtained vacuum-concentrated mixture was subjected to separation and purification through column chromatography (ethyl acetate/hexane/triethylamine, 2:1:0.1, v/v/v) using silica gel (SiO2), resulting in a benzamide compound represented by Formula 83 as a desired product (VVZ-078; 632.5 mg, 70% yield). was slowly added the mixture was left at room temperature for 18 hours was removed through filtration The remaining solution was diluted with chloroform this diluted solution was washed with a potassium carbonate (K2CO3) solution followed by separation drying the same with sodium sulfate (Na2SO4) The obtained vacuum-concentrated mixture was subjected to separation and purification through column chromatography (ethyl acetate/hexane/triethylamine, 2:1:0.1, v/v/v)

実験手順: After cooling N,N-dimethyl-1-phenylethane-1,2-diamine represented by Formula 101 (292 mg, 1.78 mmol, purchased from Alfa Aesar Co.) and triethylamine (0.55 mL, 3.95 mmol) in THF (8 mL) at 0° C. under a nitrogen atmosphere, 4-n-benzyloxy-3,5-dimethoxybenzoic acid chloride represented by Formula 85 (606 mg, 1.98 mmol) prepared in Preparative Example 1 in THF (12 mL) was slowly added to the cooled solution. After agitating the above solution at the same temperature for 30 minutes, this was left alone at room temperature for 18 hours. A precipitate generated during the reaction was filtered and discarded, the remaining solution was diluted using chloroform and washed with a potassium carbonate solution, followed by separation and drying with sodium sulfate. The solvent was removed again under reduced pressure. The obtained vacuum-concentrated mixture was subjected to separation and purification through column chromatography (ethyl acetate/hexane/triethylamine, 2:1:0.1, v/v/v) using silica gel (SiO2), resulting in a benzamide compound represented by Formula 19 as a desired product (VVZ-020; 451.3 mg, 52% yield). was slowly added to the cooled solution this was left alone at room temperature for 18 hours was filtered the remaining solution was diluted washed with a potassium carbonate solution followed by separation drying with sodium sulfate The solvent was removed again under reduced pressure The obtained vacuum-concentrated mixture was subjected to separation and purification through column chromatography (ethyl acetate/hexane/triethylamine, 2:1:0.1, v/v/v)
