Reaction Steps

To a solution of 3,4-difluoroaniline (0.60 g, 4.65 mmol) in 1,2-dichloroethane (5 ml) were added 4-formylimidazole (0.67 g, 6.97 mmol), sodium triacetoxyborohydride (1.97 g, 9.29 mmol) and acetic acid (0.05 ml). The reaction mixture was stirred at 50° C. for 4 h. The reaction mixture was then concentrated in vacuo and the residue was purified using flash chromatography (column: Isolute® Flash-NH2 (Separtis); eluent: methanol/dichloromethane gradient) to yield an off-white solid (284 mg, 29%); MS (ISP): 210.1 ((M+H)+.).
