To a mixture of 4-(bicyclo[1.1.1]pentan-1-ylamino)-2-(methylsulfinyl)pyrimidine-5-carboxamide and 4-(bicyclo[1.1.1]pentan-1-ylamino)-2-(methylsulfonyl)pyrimidine-5-carboxamide (300 mg) and (1S,3R)-3-aminocyclohexanol (152 mg, 1.32 mmol; prepared as described in Tetrahedron: Asymmetry 15:2051-2056 (2004)) in NMP (10 mL) was added DIEA (426 mg, 3.3 mmol). The resulting mixture was stirred at 100° C. overnight. The reaction mixture was purified by preparative HPLC to give the desired product (230.2 mg, 0.73 mmol, yield 66%). 1H NMR (400 MHz, CD3OD) δ ppm 8.29 (s, 1H), 3.91-3.89 (m, 1H), 3.69-3.62 (m, 1H), 2.50 (s, 1H), 2.29-2.25 (m, 1H), 2.20 (s, 6H), 1.97-1.83 (m, 3H), 1.41-1.21 (m, 4H); MS (ESI) m/z=318.2 [M+1]+.
