A suspension of (2-(4-chlorophenylamino)pyrimidin-5-yl)methanol (0.15 g, 0.636 mmol) and Et3N (0.177 ml, 1.273 mmol) in DCM (6.4 mL) was cooled to 0° C. and methanesulfonyl chloride (0.099 mL, 1.273 mmol) was added. The reaction was stirred for 1.5 h while warming to room temperature. The mixture was diluted with DCM and quenched with sat. NaHCO3. The organic layer was isolated and dried over Na2SO4, then concentrated to give crude 5-(chloromethyl)-N-(4-chlorophenyl)pyrimidin-2-amine as a yellow solid (0.1 g, 62%). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 8.46 (2H, s), 7.58 (2H, d, J=8.78 Hz), 7.31 (2H, d, J=8.78 Hz), 7.25 (1H, br. s.), 4.53 (2H, s).
