Participants

Reaction Steps

With the exclusion of atmospheric moisture, 50 g (0.18 mol) of methyl 2-chloro-3-formyl-4-sulfonylmethylbenzoate, 220 g (3.6 mol) of nitromethane, 216 g (3.6 mol) acetic acid and 7 g (91 mmol) of ammonium acetate are stirred at 85° C. The reaction mixture is poured into 2 l of distilled water and extracted with diethyl ether. The organic phase is washed with saturated aqueous sodium bicarbonate solution, dried with sodium sulfate, filtered and freed from the solvent under reduced pressure. The crude product is recrystallized from n-hexane/ethyl acetate. Yield: 13.1 g, m.p. 147-150° C.
