Procedure

608.7 g (2.03 mol) of 1-(4-fluorophenyl)-2-dimethylamino-2-benzyl-butan-1-one (Example 1, B), 354.2 g (4.06 mol) of morpholine, 562 g (4.06 mol) of K2CO3 and 2000 ml of dimethylsulfoxide are heated at 160° for 12 hours, with stirring. After this time, a sample no longer shows any starting ketone in a thin-layer chromatogram. The reaction solution is cooled to room temperature, poured onto ice and extracted with methylene chloride. The organic phase is dried over MgSO4, filtered and evaporated. The oily residue crystallizes from ethanol. The product melts at 111°-119°.
