A mixture of 3-Chloro-2-butanone (2.1 g, 10.0 mmol) and 4-methoxybenzamide (0.30 g, 1.0 mmol) was heated at 115° C. for 15 h under nitrogen atmosphere. After the completion of the reaction mixture (TLC monitoring), the reaction mixture was evaporated to dryness under reduced pressure and the residue was purified over silica gel (230-400 M, 20% EtOAc-Hexane) to get the desired product (0.17 g, 42%) as a white solid. The corresponding chloro derivative was also prepared by the same general method.
