Procedure
A mixture of (2E)-N-(3,4-dichlorophenyl)-3-phenyl-2-propenamide (4.0 g, 13.7 mmol) and AlCl3 (9.1 g, 68.5 mmol) was heated slowly until the mixture became liquefied and then subsequently congealed to form a solid cake. Ice was slowly added to break up the hardened material. The mixture was vigorously stirred for 2 h. The precipitate was collected and washed with 2 N HCl solution, water, and ether to obtain a white mixture of product A and B above (2.8 g, 96%), MS (ES) m/e 215 [M+H]+.
