A mixture of 4-(((1R,4S)-4-hydroxy-3,3-dimethylcyclohexyl)amino)-2-(methylsulfonyl)pyrimidine-5-carbonitrile (80 mg, crude), 3-(2-aminoethyl)-5-chloropyridine 1-oxide (80 mg, crude) and DIEA (169 mg, 1.31 mmol) in THF (2 mL) was stirred at 85° C. in a microwave reactor for 1 h. After cooling to room temperature, the reaction mixture was concentrated and the residue purified by standard methods to afford the title product (32.6 mg, 0.08 mmol, 22% yield, over three steps). 1H NMR (400 MHz, CD3OD) δ (ppm) 8.30 (s, 1H), 8.16 (s, 1H), 8.08 (s, 1H), 7.51 (s, 1H), 4.32-4.25 (m, 1H), 3.77-3.65 (m, 2H), 3.42-3.40 (s, 1H), 2.99-2.93 (m, 2H), 1.95-1.50 (m, 6H), 1.03 (s, 3H), 0.99 (s, 3H). MS (ESI) m/z 417.2 [M+H]+.
