Participants

Reaction Steps

2-Methoxy-3-(5-methyl-2-nitrophenoxy)benzaldehyde (0.36 g, 1.3 mmol), methylamine (2M in methanol, 3.0 mL, 6.0 mmol) and sodium cyanoborohydride (100 mg, 1.6 mmol) were stirred at ambient temperature in a 1% acetic acid/methanol solution (50 mL) for 18 h. The solvent was removed in vacuo. The residue was treated with 10% sodium carbonate solution and extracted with ethyl acetate. The ethyl acetate layer was separated and fumaric acid (0.14 g, 1.2 mmol) was added. After the solvent was removed in vacuo, the residue was triturated with hot methanol and allowed to cool overnight. The filtrate was collected, the solvent removed in vacuo. The residue was triturated with ethyl acetate overnight, collected by filtration, and dried to give [2-methoxy-3-(5-methyl-2-nitrophenoxy)benzyl]methylamine fumarate (195 mg, 38%) as a beige solid.
