Participants

Reaction Conditions

Reaction Steps

Acetyl chloride (6.5 ml, 0.09 mol) was added dropwise to methanol (130 ml) at −15° C. temperature. The reaction mixture was stirred for 30 min. simultaneously allowing to warm up to 0° C. 3-(3-Nitro-phenyl)-acrylic acid (21) (25 g, 0.13 mol) was added by small portions to the mixture at 0° C. and the resulting reaction mixture was stirred overnight at ambient temperature. The forming precipitate was filtered, washed with methanol and dried affording the title compound in a form of white crystals (26.58 g, 98%).
