実験手順

A solution of LiAlH4 in THF (1.0 M, 36 mL, 36 mmole) was added slowly to a solution of N,1-dimethyl-1H-indazole-3-carboxamide (3.42 g, 18 mmole) in dry THF (90 mL) at RT. After 2 hr the mixture was heated to a gentle reflux. After 4 hr the mixture was cooled to RT and quenched by dropwise addition of 2.0 M NaOH until a white solid had formed. The mixture was dried (MgSO4) and filtered, and the filtrate was concentrated under reduced pressure to give the title compound (3.28 g, 100%) as an oil: MS (ES) m/e 176 (M+H)+.
