Procedure

A mixture of 4-(((1R,4S)-4-hydroxy-3,3-dimethylcyclohexyl)amino)-2-(methylsulfonyl)pyrimidine-5-carbonitrile (90 mg, 0.28 mmol), 2-(4-(2,2-difluoropropoxyl)phenyl)ethanamine (70 mg crude) and DIEA (85 mg, 0.66 mmol) in THF (2 mL) was stirred at 100° C. in a microwave reactor for 1.5 h. After cooling to room temperature, the reaction mixture was concentrated and the residue was purified by standard methods to give the title product (38.6 mg, 0.084 mmol, 28% yield). 1H NMR (400 MHz, CD3OD) δ (ppm) 8.15-7.97 (m, 1H), 7.15 (d, J=8.4 Hz, 2H), 6.87 (d, J=8.4 Hz, 2H), 4.39-4.22 (m, 1H), 4.12 (t, J=11.6 Hz, 2H), 3.66-3.49 (m, 2H), 3.41-3.35 (m, 1H), 2.88-2.77 (t, J=7.2 Hz, 2H), 1.96-1.82 (m, 1H), 1.80-1.42 (m, 8H), 1.03-0.95 (m, 6H). MS (ESI) m/z 460.2 [M+H]+.
