実験手順: N-(Benzyloxycarbonyloxy)succinimide (8.9 g, 35.7 mmole) was added to a solution of 3-(methylaminomethyl)-1H-indole (5.2 g, 32.5 mmole) and triethylamine (5.0 mL. 65.7 mmole) in DMF (100 mL) at RT. The reaction was stirred overnight then was concentrated in vacuo. The residue was diluted with water and the mixture was extracted with ethyl acetate. The combined extracts were dried over Na2SO4 and concentrated. Flash chromatography on silica gel (33% ethyl acetate/hexanes) gave the title compound (7.0 g, 74%) as an off-white solid: MS (ES) m/e 295 (M+H)+. then was concentrated in vacuo The residue was diluted with water the mixture was extracted with ethyl acetate The combined extracts were dried over Na2SO4 concentrated

The reaction was held at 0° C. for ten minutes, then was stirred overnight at RT. The solution was concentrated in vacuo and the residue was diluted with water. The solution was extracted with ethyl acetate, and the combined organic extracts were washed with brine and dried over Na2SO4. The title compound (0.64 g, 80%) was obtained as a light yellow solid: MS (ES) m/e 215 (M+H)+. The reaction was held at 0° C. for ten minutes The solution was concentrated in vacuo the residue was diluted with water The solution was extracted with ethyl acetate the combined organic extracts were washed with brine dried over Na2SO4

実験手順: N-(Benzyloxycarbonyloxy)succinimide (8.9 g, 35.7 mmole) was added to a solution of 3-(methylaminomethyl)-1H-indole (5.2 g, 32.5 mmole), from Preparation 16, and triethylamine (5.0 mL, 65.7 mmole) in DMF (100 mL) at RT. The reaction was stirred overnight then was concentrated in vacuo. The residue was diluted with water and the mixture was extracted with ethyl acetate. The combined extracts were dried over Na2SO4 and concentrated. Hash chromatography on silica gel (33% ethyl acetate/hexanes) gave the title compound (7.0 g, 74%) as an off-white solid: MS (ES) m/e 295 (M+H)+. then was concentrated in vacuo The residue was diluted with water the mixture was extracted with ethyl acetate The combined extracts were dried over Na2SO4 concentrated

実験手順: To a solution of indole-3-carboxaldehyde (5.4 g, 34.1 mmole) in MeOH (30 mL) was added a solution of 2.0 M CH3NH2 in MeOH (51.3 mL, 102.6 mmole). The reaction was stirred at RT overnight, then was concentrated to a light yellow oil. This oil was dissolved in EtOH (40 mL), and NaBH4 (1.3 g, 34.1 mmole) was added. After 16 hrs the reaction was concentrated to a slurry and dissolved in 10% Na2CO3(100 mL). The aqueous solution was extracted with EtOAc (2×200 mL) and the combined organic fractions were dried over Na2SO4 and concentrated. Drying in high vacuum left the title compound (5.2 g, 94%) as a faintly yellow oil: MS (ES) m/e 161 (M+H)+. was concentrated to a light yellow oil This oil was dissolved in EtOH (40 mL) After 16 hrs the reaction was concentrated to a slurry dissolved in 10% Na2CO3(100 mL) The aqueous solution was extracted with EtOAc (2×200 mL) the combined organic fractions were dried over Na2SO4 concentrated Drying in high vacuum left the title compound (5.2 g, 94%) as a faintly yellow oil
