Procedure

Into a 50-mL round-bottom flask, was placed a solution of 4-chloro-6-(2-nitro-5-(piperidin-1-yl)phenyl)pyrimidine 3.1b (500 mg, 1.57 mmol, 1.00 equiv) in N,N-dimethylformamide (10 mL), m-methylbenzylamine (285 mg, 2.36 mmol, 1.50 equiv), and potassium carbonate (650 mg, 4.71 mmol, 3.00 equiv). The resulting solution was stirred overnight at 80° C. The solids were filtered out. The resulting mixture was concentrated under vacuum. The residue was dissolved in 50 mL of ethyl acetate. The resulting mixture was washed with 2×50 mL of water. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column and eluted with ethyl acetate/petroleum ether (1:5). This resulted in 0.5 g (79%) of N-(3-methylbenzyl)-6-(2-nitro-5-(piperidin-1-yl)phenyl)pyrimidin-4-amine. as yellow oil.
