Reaction Steps

4-[4-(4-Benzyloxy-2-hydroxy-2-methylbutoxy)phenyl]piperazine-1-carboxylic acid tert-butyl ester (6.16 g, 13.1 mmol), palladium hydroxide on carbon (0.62 g) and ethanol (62 ml) were mixed and stirred at 50 to 60° C. under a hydrogen atmosphere for 9 hours. The mixture was filtered through Celite to remove the catalyst, and the filtrate was concentrated. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=100:0→0:100) to afford the title compound as a colorless powder (3.75 g).
