Procedure

A mixture of ethyl 2,4-dichloropyrimidine-5-carboxylate (0.221 g, 1.00 mmol), 3-aminomethyl-1-N-CBz-piperidine (0.248 g, 1.00 mmol) and triethylamine (0.300 mL, 2.15 mmol) in CH3CN (10 mL) was stirred at room temperature for 20 h. Water and EtOAc were added. The organic phase was separated, washed with 1N HCl, then with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give ethyl 4-((1-(benzyloxycarbonyl)piperidin-3-yl)methylamino)-2-chloropyrimidine-5-carboxylate (0.382 g).
