Conditions

Temperature: 80 °C

Procedure

N-(4-Chlorophenyl)-beta-(2-methanesulfonyloxyethyl)-N-methyl-benzenepropanamide (0.93 g) in DMF (10 mL) was treated with N-phenylmethylpiperazine (1.03 g) and the mixture heated at 80° C. for 2 hours. The cooled reaction mixture was diluted the EtOAc (50 mL) and water (50 mL) and the aqueous phase removed. The aqueous layer was extracted with EtOAc (2×50 mL) and the combined organic extracts, washed with water (50 mL), dried over MgSO4, filtered and concentrated under reduced pressure to give an oil. Silica gel chromatography eluting with 10% MeOH:CH2Cl2 gave the title compound (0.5 g). Mass spectrum (FAB): 476.3.
