Reaction Steps

4-phenyl-piperidine-4-carboxylic acid hydrochloride (from example 20.6) (2.67 g, 11 mmol) and methanol (35 mL) were combined. SOCl2 (0.9 mL, 12.34 mmol, 1.1 eq.) was added dropwise. The reaction was heated at reflux for 18 h. The reaction was concentrated in vacuo to obtain a residue. The residue was slurried in diethyl ether, filtered, and the solids were rinsed with diethyl ether to give the title compound.
