Reaction Steps

To a solution of 4-((1R,3S)-3-hydroxycyclohexylamino)-2-(methylsulfonyl)pyrimidine-5-carboxamide (1.2 g, 3.8 mmol; synthesis described herein) and 4-methoxybicyclo[2.2.2]octan-1-amine hydrochloride (600 mg, 3.1 mmol) in NMP (12 mL) was added DIEA (1.03 g, 8 mmol). The resulting mixture was stirred at 130° C. under microwave irradiation for 3 h. The resulting mixture was purified by reverse phase column chromatography to give the desired product (230 mg, 0.6 mmol, 15.5% yield). 1H-NMR (400 MHz, CDCl3) δ ppm 8.70 (brs, 1H), 8.08 (s, 1H), 5.40 (brs, 2H), 5.01 (br. s, 1H), 3.99-3.96 (m, 1H), 3.75-3.70 (m, 1H), 3.19 (s, 3H), 2.37-2.34 (m, 1H), 2.15-2.11 (m, 6H), 1.99-1.97 (m, 2H), 1.90-1.86 (m, 1H), 1.80-1.76 (m, 6H), 1.38-1.22 (m, 4H). MS (ESI) m/z=390.2[M+1]+.
