実験手順

4-((1R,3S)-3-Hydroxycyclohexylamino)-2-(methylsulfonyl)pyrimidine-5-carboxamide (0.740 g, 2.354 mmol; synthesis described herein), 4-methyltetrahydro-2H-pyran-4-amine hydrochloride (0.892 g, 5.88 mmol), DIEA (1.645 mL, 9.42 mmol) and NMP (20 mL) were combined and heated for 1 h at 180° C. in a microwave. The solvent was concentrated under reduced pressure and the residue was purified by column chromatography (0-10% methanol in DCM) to afford 4-((1R,3S)-3-hydroxycyclohexylamino)-2-(4-methyltetrahydro-2H-pyran-4-ylamino)pyrimidine-5-carboxamide (88 mg, 0.252 mmol, 10.70% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.96 (br. s., 1H), 8.35 (s, 1H), 6.76 (br. s., 1H), 4.65 (d, J=4.69 Hz, 1H), 3.56 (dd, J=3.32, 6.83 Hz, 4H), 3.40-3.47 (m, 1H), 2.20-2.29 (m, 2H), 2.10 (d, J=10.93 Hz, 1H), 1.76-1.89 (m, 2H), 1.66-1.73 (m, 1H), 1.50-1.59 (m, 2H), 1.39 (s, 3H), 1.16-1.26 (m, 1H), 1.03-1.12 (m, 3H). MS (ESI) m/z 350.4 [M+1]+.
