Reaction Conditions

Reaction Steps

To a stirred solution of 3-fluoro-2-methylbenzaldehyde (150 g, 1.2 mol) in IMS (600 mL) was added 3-methoxyacetophenone (163 g, 1.2 mol). NaOH (10% aq, 750 mL) was added over 40 min using a water bath to maintain a temperature between 18-25° C. The mixture was stirred vigorously at room temperature for 15 h and a thick precipitate was formed. The solid was isolated by filtration, broken up with a mortar and pestle, and washed IMS and water. After drying at 45° C. for 48 h, 273 g (84% yield), the desired product (E)-3-(3-fluoro-2-methylphenyl)-1-(3-methoxyphenyl)prop-2-en-1-one was obtained (characterized by LCMS and 1H NMR, LRMS (M+H+) m/z=271.1.
