Reaction Conditions

Reaction Steps

At 0° C., to a mixture of nitromethane 150 ml and propionic acid o-tolyl ester (described in Reference Preparation example 113) 14 g was added aluminum trichloride 30 g. The resulting mixture was heated to 50° C. and was stirred for twelve hours. To the reaction mixture was added ice water 200 ml and the resulting mixture was extracted with ethyl acetate. The organic layer was washed with water and was dried over anhydrous magnesium sulfate, and was then concentrated under reduced pressure. The resulting residue was subjected to a silica gel column chromatography to give 1-(4-hydroxy-3-methyl-phenyl)-propane-1-one 8.8 g.
