1 Gram of 1-(2-hydroxyethyl)-4-benzamidopiperidine suspended in 2 milliliters of dry benzene was treated with 0.62 gram of thionyl chloride. The stirred mixture was refluxed for 3 hrs., then cooled and filtered to give the title compound as a light grey solid. Crystallisation from ethanol-ether of this hydrochloride gave 0.8 grams (62%) of pale yellow needles, melting point 238.5° C.
