Participants

Reaction Steps

A mixuture of 297 mg (1 mmol) of 3-(2-methoxyphenyl)-4-(3-nitrophenyl)-3-butene-2-one, 575 mg (5 mmol) of methyl 3-aminocrotonate, 273 mg (2 mmol) of zinc chloride, and 500 mg of Molecular Shieves 4A was added to 1,4-dioxane. This reaction mixture was refluxed with application of heat in an inert atmoshpere for 5 hours. The reaction mixture was then cooled to room temperature and neutralized with a saturated aqueous solution of sodium hydrogencarbonate, followed by extraction with chloroform. The solvents contained in the extract were distilled off and the residue was chromatographed on a silica gel column, whereby the captioned compound was obtained. The yield was 216 mg (55%).
