Reaction Steps

1-Acetylpiperidin-4-ol (Preparation 193, 10 g, 70 mmol) in N,N-dimethylformamide (50 ml) was added dropwise to a stirred suspension of sodium hydride (50% wt dispersion in oil, 3.8 g, 80 mmol) in N,N-dimethylformamide (50 ml) at room temperature under nitrogen. After stirring the reaction mixture for 3 hours, 4-fluorobenzyl chloride (10.1 g, 70 mmol) in N,N-dimethylformamide (50 ml) was added dropwise and the reaction mixture was stirred for a further 4 h. The reaction mixture was filtered and the filtrate was evaporated to give an orange oil. Water was added and the mixture was extracted with petroleum ether (3×100 ml) and then with diethyl ether (3×100 ml). The combined organic extracts were washed with sodium hydroxide solution (1 M, 3×100 ml), before drying (Na2SO4) and concentrating to give the title compound as an oil (10.1 g, 99%).
