Reaction Steps
To a solution of 3-nitrobenzaldehyde (49 g, 295 mmol) and (diethoxy-phosphoryl)-acetic acid ethyl ester (72.74 g, 325 mmol) in DMF (300 ml) at 0° C. was added NaH (14.2 g, 354 mmol) portionwise and stirred for 1.5 hrs at r.t. The reaction mixture was poured into water to give colorless crystals, which were collected by filtration and washed with water and hexane to give the product ethyl 3-(3-nitrophenyl)acrylate (63 g, yield 96.6%). 1H NMR MeOD 400 MHz. δ 8.42-7.62 (m, 4H), 7.74-7.70 (d, 1H), 6.68-6.64 (d, 1H), 4.28-4.22 (m, 2H), 1.34-1.30 (m, 3H).
