反応手順
To a stirred solution of 1-methyl-2-indolecarboxylic acid (100 mg, 0.57 mmol) in methylene chloride (1 mL) was added N-methylmorpholine (0.063 mL, 0.57 mmol) followed by (S)-(−)-2-amino-3-phenyl-1-propanol (86 mg, 0.57 mmol), 1-hydroxybenzotriazole hydrate (81 mg, 0.60 mmol), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (120 mg, 0.63 mmol). The resulting mixture was stirred at room temperature for 20 h. The reaction was diluted with methylene chloride and washed sequentially with 10% citric acid, saturated NaHCO3, water, and brine. The organic layer was dried over Na2SO4 and concentrated in vacuo to give a crude oil. Trituration of the crude oil with methanol and diethyl ether afforded the title compound (68%, 119.7 mg) as an off-white solid. MS (ES) m/e 309.4 [M+H]+.
