Reaction Steps
To a solution of 4-(tert-butoxycarbonylaminomethyl)piperidine (9.70 g) in toluene (160 ml) were added 3-ethylenedioxy-3-(4-methoxyphenyl)propyl bromide (13.0 g) and potassium carbonate (18.8 g), and the resulting mixture was stirred at 80° C. for 16.5 hr. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (chloroform:methanol=20:1) to give 14.7 g of 1-(3-ethylenedioxy-3-(4-methoxyphenyl)propyl)-4-(tert-butoxycarbonylaminomethyl)piperidine.
