Procedure

A mixture of 4-(((1R,4S)-4-hydroxy-3,3-dimethylcyclohexyl)amino)-2-(methylsulfonyl)pyrimidine-5-carbonitrile (90 mg, crude), 2-(1-methyl-1H-indol-3-yl)ethanamine (60 mg, 0.34 mmol), and DIEA (72 mg, 0.56 mmol) in THF (3 mL) was stirred at 100° C. in a microwave reactor for 1 h. After cooling to room temperature, the reaction mixture was concentrated and the residue was purified by standard methods to afford the title compound (21.5 mg, 0.051 mmol, 15% yield). 1H NMR (400 MHz, CD3OD) δ (ppm) 8.00 (s, 1H), 7.52 (d, J=8.0 Hz, 1H), 7.30 (d, J=8.0 Hz, 1H), 7.14 (t, J=7.6 Hz, 1H), 7.00 (t, J=8.0 Hz, 1H), 6.94 (s, 1H), 4.28-4.23 (m, 1H), 3.75 (s, 3H), 3.75-3.62 (m, 2H), 3.02 (t, J=7.6 Hz, 1H), 1.82-1.26 (m, 6H), 1.02-0.87 (m, 6H). MS (ESI) m/z 419.2 [M+H]+.
