At 0° C., NaH (60%, 125 mg, 3.06 mmol, 1.0 eq.) was added to 3-hydroxy-5-methyl-benzonitrile (408 mg, 3.06 mmol) in 10 mL of DMF solution. The reaction mixture was stirred at 0° C. for 5 minutes. 2,4,6-Trichloro-5-isopropyl-pyrimidine (691 mg, 3.06 mmol) was then added. The reaction mixture was stirred at 0° C. for 30 minutes. Ethyl acetate was added to the reaction mixture, which was then washed with brine. The organic layer was concentrated and purified (silica gel, 0-50% EtOAc/hexane) to give a white solid (868 mg, 88%). LC-MS shows 322.1 (M+1). 1H NMR (300 MHz, CDCl3): δ 7.41 (s, 1H), 7.26 (s, 1H), 7.19 (s, 1H), 3.60 (m, 1H), 2.42 (s, 3H), 1.42 (d, 6H).
