Reaction Steps

2-[2-(Benzyloxy)ethyl]-2-methyloxirane (2.60 g, 13.5 mmol), 4-(4-hydroxyphenyl)piperazine-1-carboxylic acid tert-butyl ester (4.14 g, 14.9 mmol), tripotassium phosphate (1.15 g, 5.4 mmol) and ethanol (26 ml) were mixed and stirred at 80 to 90° C. overnight. The reaction mixture was poured into water, followed by extraction with ethyl acetate. The organic layer was washed with a saturated sodium chloride aqueous solution, dried over sodium sulfate, and concentrated. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=100:0→30:70) to afford the title compound as a pale yellow oil (6.16 g).
