Reaction Steps

To a solution of 2,4-dichloro-5-methylpyrimidine (0.75 g, 4.6 mmol) in dry DMF (15.5 mL) was added tert-butyl piperazine-1-carboxylate (0.9 g, 4.85 mmol) followed by DIEA (0.91 mL, 5.5 mmol) at 0° C., and the mixture was stirred to room temperature overnight. LCMS showed the reaction was completed. The reaction was diluted with water (120 mL), and the solid was filtered. The residue was washed with water and dried to give the title compound (1.386 g, 96%) as a white solid. MS (ES+) C14H21ClN4O2 requires: 312. found: 313 [M+H]+
