To a solution of tert-butyl 3-{[(benzyloxy)carbonyl](2-methylpropyl)amino}-5-(hydroxymethyl)piperidine-1-carboxylate (4.6 g) and triethylamine (2.3 ml) in ethyl acetate (25 ml) was added acetyl chloride (0.94 ml) under ice-cooling, and the mixture was stirred at room temperature for 5 hr. The reaction mixture was diluted with saturated aqueous sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the object compound (5.09 g).
