Participants

Reaction Steps

A solution of 3,5-dimethoxybenzaldehyde (34.5 g., 0.208 mole) and nitromethane (12.69 g., 0.208 mole) in 40 ml. of MeOH was cooled to 0° under N2. A solution was prepared by dissolving NaOH (8.43 g., 0.211 mole) in 10 ml. of H2O then diluting to 20 ml. with ice-water. This solution was then added dropwise to the methanol mixture. After 15 minutes the reaction was diluted with ice-H2O and added slowly to a solution of 40 ml. concentrated HCl in 60 ml. H2O. The resulting precipitate (44 g.) was filtered and recrystallized from methanol to give 28.6 g. of product, m.p. 132°; reported, J. Org. Chem. 27, p. 376 (1962), m.p. 133.5-134.5.
