Procedure
A vessel was charged with 2,4-dichloro-5-methylpyrimidine (5.0 g, 28 mmol), 2-amino-N-(1-methylethyl)benzamide (5.46 g, 34.3 mmol), di-isopropyl-ethylamine (7.0 mL, 42 mmol) and 2-(methyloxy)ethanol (30 mL) and sealed and heated with stirring at 130° C. for 36 hours. The reaction was cooled to room temperature and 50 mL water was added dropwise to afford a milky white solution, which was heated to 100° C. to induce precipitation. The solution was cooled and the solid collected by filtration. The collected solid was washed successively with water (2×50 mL) and hexane (3×50 mL). After drying, a white solid was collected (6.56 g, 77% yield) and identified as 2-[(2-chloro-5-methyl-4-pyrimidinyl)amino]-N-(1-methylethyl)benzamide. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.51 (1H, s) 8.56-8.63 (2H, m) 8.15 (1H, s) 7.81 (1H, dd, J=7.83, 1.52 Hz) 7.58 (1H, dd, J=15.66, 1.52 Hz) 7.17 (1H, dd, J=15.28, 1.14 Hz) 4.13 (1H, dd, J=14.02, 6.69 Hz) 2.18 (3H, s) 1.18 (6H, d, J=6.57 Hz).
