A mixture of 4-(bromomethyl)-3,5-dichloropyridine hydrobromide (2.9 g, 10.5 mmol), 4-amino-6-methylpyrimidine-2-thiol (1.0 g, 7.1 mmol), and triethylamine (3 mL, 21.5 mmol) in absolute EtOH (80 mL) was stirred at room temperature overnight. The mixture was evaporated, co-evaporated with EtOAc (20 mL), and dried in vacuo. The solid residue was treated with water (150 mL). The solid product was recovered by filtration, washed with water (2×25 mL), diethyl ether (2×25 mL), and hexanes (2×25 mL), and dried in vacuo, affording the title compound (1.9 g, 92% yield); 1H NMR (400 MHz, DMSO-d6): δ 2.29 (s, 3H), 4.78 (s, 2H), 6.29 (s, 1H), 8.45 (s (br), 2H), 8.69 (s, 2H); M+302.
