1,3-Propanediamine, N'-(ethylcarbonimidoyl)-N,N-dimethyl-, monohydrochloride → 2-nitro-5-(piperidin-1-yl)-N-(2-(3-(trifluoromethyl)phenyl)pyrimidin-5-yl)benzamide

참여 물질

반응 단계

To 2-(3-(trifluoromethyl)phenyl)pyrimidin-5-amine (750 mg, 3.14 mmol, 1.00 equiv) in dichloromethane (50 mL) was added 2-nitro-5-(piperidin-1-yl)benzoic acid (1.18 g, 4.72 mmol, 1.50 equiv), EDC.HCl (1.2 g, 6.28 mmol, 2.00 equiv) and 4-dimethylaminopyridine (770 mg, 6.31 mmol, 2.00 equiv) and the resulting solution was stirred for 48 h at room temperature. The reaction was diluted with 25 mL of water and then extracted with 2×25 mL of dichloromethane. The organic layers were combined, dried over sodium sulfate, concentrated, and the residue was applied onto a silica gel column and eluted with ethyl acetate/petroleum ether (1:30˜1:5) to give 0.4 g (27%) of product as a yellow solid.
