Participants

Reaction Steps

2-(4-Formyl-3-phenyl-phenoxy)-4-trifluoromethyl-benzonitrile (0.117 g, 0.35 mmol), methylamine (2M in methanol, 0.233 mL, 1.05 mmol) and sodium cyanoborohydride (0.025 g, 0.39 mmol) were stirred at ambient temperature in a 1% acetic acid/methanol solution for 20 h. The solvent was removed in vacuo. The residue was treated with 10% sodium carbonate solution and extracted with ethyl acetate. Fumaric acid (0.032 g, 0.28 mmol) was added to the separated ethyl acetate layer and the solvent removed in vacuo. The residue was triturated with ethyl acetate overnight, filtered and dried to give 2-(4-methylaminomethyl-3-phenyl-phenoxy)-4-trifluoromethyl-benzonitrile fumarate (75 mg, 61%) as a white solid.
