Procedure

To a solution of 4-(((1R,4R)-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 via standard methods to afford the title compound (34.2 mg, 0.074 mmol, 30% yield). 1H NMR (400 MHz, CD3OD) δ (ppm) 8.70 (s, 1H), 8.34-8.32 (m, 1H), 8.13 (s, 1H), 4.70 (t, J=12.0 Hz, 1H), 4.64-4.59 (m, 2H), 4.18-4.15 (m, 1H), 1.81-1.74 (m, 3H), 1.68-1.41 (m, 6H), 1.32-1.30 (s, 3H), 0.92-0.85 (s, 6H). MS (ESI) m/z 462.2 [M+H]+.
