Procedure

To a solution of 4-(((1R,4S)-4-hydroxy-3,3,4-trimethylcyclohexyl)amino)-2-(methylsulfonyl)pyrimidine-5-carbonitrile (90 mg, crude) in THF (2.8 mL) was added (4-(2,2-difluoropropoxyl)pyrimidin-5-yl)methanamine (50 mg, 0.246 mmol) and DIEA (100 mg, 0.738 mmol). The resulting mixture was stirred at 100° C. in a microwave reactor for 2 h. The solvent was evaporated and the residue was purified by standard methods to afford the title compound (38.7 mg, 0.084 mmol, 34% yield). 1H NMR (400 MHz, CD3OD) δ (ppm) 8.90 (s, 1H), 8.57-8.54 (s, 1H), 8.34 (s, 1H), 4.92 (t, J=12.0 Hz, 1H), 4.81-4.78 (m, 2H), 4.34-4.28 (m, 1H), 2.04-1.95 (m, 3H), 1.92-1.68 (m, 6H), 1.47-1.45 (m, 3H), 1.09-1.01 (m, 6H). MS (ESI) m/z 462.2 [M+H]+.
