Reaction Steps

To a solution of 1-methyl-N-cyclopropylindole-2-carboxamide (2.1 g, 9.8 mmole) in dry THF (40 mL) was added dropwise a solution of 1.0 M LiAlH4 in THF (2.2 mL, 22 mmole). The reaction mixture was heated at reflux overnight, then was cooled and quenched with 10% NaOH. The mixture was filtered and the filtrate was concentrated in vacuo. Flash chromatography on silica gel (5% MeOH/CH2Cl2) gave the title compound (0.65 g, 33%) as a viscous oil: MS (ES) m/e 203 (M+H)+.
