実験手順: (2-Methylphenoxy)acetic acid (32 mg, 0.193 mmol) was made into acid chloride in a conventional manner. By using 5-(4-aminophenyl)-1H-naphtho[1,2-b][1,4]diazepine-2,4(3H,5H)-dione (30 mg, 0.095 mmol) obtained in Example 1, and (2-methylphenoxy)acetic acid chloride mentioned above, the title compound (21 mg, yield 48%) was obtained in the same manner as that of Example 1.

反応条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Toluene (20 ml) and thionyl chloride (1 ml) were added to commercially available 2-(2-methylphenoxy)acetic acid (80 mg), and the mixture was heated at 100° C. for one hr. The solvent was removed by distillation, and 2-(2-methylphenoxy)ethanoyl isothiocyanate was prepared using the resultant 2-(2-methylphenoxy)ethanoyl chloride as a starting compound according to the description of the literature. 4-[(6,7-Dimethoxy-4-quinazolinyl)oxy]aniline (50 mg) was dissolved in toluene (5 ml) and ethanol (1 ml) to prepare a solution. A solution of 2-(2-methylphenoxy)ethanoyl isothiocyanate in ethanol (1 ml) was then added to the solution, and the mixture was stirred at room temperature for 2 hr. The reaction solution was concentrated, and the residue was purified by chromatography on silica gel using chloroform/acetone for development to give the title compound (37 mg, yield 44%). The solvent was removed by distillation, and 2-(2-methylphenoxy)ethanoyl isothiocyanate was prepared The reaction solution was concentrated the residue was purified by chromatography on silica gel

実験手順: Oxalyl chloride (2.2 mL, 25 mM) was added to a stirred solution of (2-methylphenoxy)acetic acid (3.32 g, 20 mM) in dichloromethane (10 mL). Dry N,N-dimethylformamide (1 drop) was added to catalyse the reaction and the mixture was stirred for 16 hours. The solvent was removed by evaporation to leave (2-methylphenoxy)acetyl chloride as a pale yellow oil, which was used without further purification. the reaction The solvent was removed by evaporation

実験手順: 3-Methylanthranilic acid 1.0 g (6 mmol) was dissolved in 10% aqueous sodium hydroxide solution 27 ml and to this soulution, 2-methylphenoxyacetyl chloride 1.3 g (7.3 mmol) was added dropwise at 0° C. The resulting solution was stirred at room temperature for 5 minutes and acidified with 10% hydrochloric acid solution. Deposited crystals were collected by filtration, washed with hot water and recrystallized from ethanol to obtain 3-methyl-N-(2-methylphenoxyacetyl)anthranilic acid (melting point: 133° to 136° C.) 1.7 g (yield: 83%). was added dropwise at 0° C Deposited crystals were collected by filtration washed with hot water recrystallized from ethanol
