(E)-3-(4-methylphenyl)prop-2-enamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of (E)-3-(4-methylphenyl)-2-propenamide (8.06 g) and 1,3-dichloroacetone (6.98 g) in toluene (50 ml) were refluxed for 3 hours. After cooling, the reaction mixture was diluted with ethyl acetate, washed with water and saline, and dried over magnesium sulfate, then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: ethyl acetate-hexane 1:4) to yield the titled compound (8.44 g) as a white crystalline powder. were refluxed for 3 hours After cooling washed with water and saline dried over magnesium sulfate concentrated under reduced pressure The residue was purified by silica gel column chromatography (eluent: ethyl acetate-hexane 1:4)
