To a solution of 3-[4-(4-chlorophenyl)-4-fluoropiperidine hydrochloride (280 mg, 1.12 mmol) in methanol (5 mL) was added sodium bicarbonate (500 mg, 5.94 mmol) followed by methyl acrylate (1 mL). The resulting mixture was stirred at room temperature for 14 hours then filtered and concentrated under reduced pressure. The residue was treated with ethyl acetate (10 mL) and the resulting suspension re-filtered and concentrated under reduced pressure. This afforded methyl 3-[4-(4-chlorophenyl)-4-fluoropiperidin-1-yl]propionate as a viscous yellow oil in 94% yield, which was used without further purification.
