실험 절차

To a stirred solution of the 2-methyl-5-(2-pyrrolidine-1-yl-ethylamino)-1H-indole-3-carboxylic acid benzyl ester (147 mg, 0.39 mmol, 1.0 eq) and triethylamine (47.6 mg, 0.47 mmol, 1.2 eq) in acetonitrile in an ice-water bath was added dropwise a solution of acetyl chloride in acetonitrile. After the ice-water bath was removed, the reaction mixture was heated to reflux for overnight. After the mixture was concentrated, the residue was purified by preparative HPLC (reverse-phase, 10-100 CH3CN:H2O, 0.1% TFA) to yield the desire indole amine in 33.0% yield. Elemental Analysis: C25H29N3O3.2HCl.0.3H2O Calcd: C: 60.31; H: 6.40; N: 8.44. Found: C: 60.63; H: 6.40; N: 8.04. ESI-MS: m/z 420.78 (M+H)+.
