70 °C

Into a 100-mL round-bottom flask, was placed a solution of 6-(2-nitro-5-(piperidin-1-yl)phenyl)-N-(1-(3-(trifluoromethyl)phenyl)ethyl)pyrimidin-4-amine (400 mg, 0.85 mmol, 1.00 equiv) in acetic acid (5 mL). To this was added zinc (552 mg, 8.62 mmol, 10.00 equiv) in several batches at 70° C. The resulting solution was stirred for 1 h at 70° C. The solids were filtered out. The resulting mixture was concentrated under vacuum. The solution was adjusted to pH 8 with ammonia (1 mol/L). The resulting solution was extracted with 4×50 ml of ethyl acetate and the organic layers combined, dried over sodium sulfate, and concentrated under vacuum. The residue was applied onto a silica gel column and eluted with methanol:dichloromethane (1:50). The product was obtained as 200 mg (53%) of a black solid.
