Procedure

31 g (0.104 mol) of 4-(3-chlorobenzyloxy)phenetylamine hydrochloride are suspended in 450 ml of anhydrous ethanol. To this mixture, 9.7 g (0.104 mol) of chloroacetamide and 28.8 g (0.208 mol) of anhydrous potassium carbonate are added. After heating to reflux, stirring is continued for 40 hours. The hot mixture is filtered, then evaporated to dryness and the crude residue chromatographed on silica gel (eluant CHCl3/MeOH/conc. NH4OH; 97/3/0.3). The free compound obtained (20.2 g; 60.7%) is treated with gaseous HCl in ethanol to give a quantitative yield of the corresponding [4-(3-chlorobenzyloxy)phenetyl]aminoacetamide, hydrochloride, m.p. 248°-251° C.
