Procedure

The mixture of ethyl 2,4-dichloropyrimidine-5-carboxylate (442 mg, 2.00 mmol), 3-aminomethyl-1-N-CBz-piperidine (496 mg, 2.00 mmol) and DIEA (0.700 mL, 4.02 mmol) in CH3CN (12 mL) was stirred at room temperature for 5 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 (808 mg).
