Reaction Steps

3-Methoxypiperonal (50.0 g) is combined with 71.9 mL of nitromethane in 250 mL of acetic acid; 36 g of ammonium acetate is added, and the mixture is heated to 50° C. for 4 hrs. Solvents are removed in vacuo; the residue is taken up in water and stirred for 20 min. The solution is filtered; the filtrate is washed with water, then ether, to give 51.8 g of a yellow solid.
