Reaction Steps

To a solution of (RS)-3-hydroxy-4-(p-toluenesulfonyloxy)butyronitrile (17.0 g) in methanol (120 ml), 10 wt. % Pd on carbon (3.0 g) and conc. hydrochloric acid (30 ml) were added. The mixture was stirred in a hydrogen atmosphere of 4.0 kg/cm2 at room temperature for 20 hours. After filtrating off the catalyst, the mixture was evaporated under reduced pressure to obtain a crude product, which was purified by silica gel chromatography (Wako Gel C200, an eluent: methanol/acetone (volume ratio of 3/7) to obtain pure (RS)-3-hydroxy-4-(p-toluenesulfonyloxy)butylamine hydrochloride (18.1 g). Yield, 92 %.
