The reaction was stirred at 80° C. for 5 h in a sealed vessel and then allowed to cool to ambient temperature overnight. The reaction mixture was concentrated under reduced pressure to an oil that was purified by silica gel chromatography (0-60% ethyl acetate/hexane) to afford 2-(cyclopropylamino)-4-((1R,3R,4R)-3-hydroxy-4-methylcyclohexylamino)pyrimidine-5-carbonitrile (265 mg, 0.922 mmol, 79% yield) as a solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 6.99-8.32 (m, 3H), 4.54 (d, J=5.08 Hz, 1H), 3.85-4.13 (m, 1H), 2.80-3.03 (m, 1H), 2.58-2.75 (m, 1H), 1.50-2.08 (m, 3H), 1.03-1.42 (m, 3H), 0.88 (d, J=6.25 Hz, 4H), 0.29-0.68 (m, 4H).
