Reaction Steps

To a mixture of 4-(tert-butylamino)-2-(methylsulfonyl)pyrimidine-5-carboxamide (250 mg, 0.918 mmol; synthesis described herein) and (1S,3R)-3-aminocyclohexanol (138 mg, 1.2 mmol; prepared as described in Tetrahedron: Asymmetry 15:2051-2056 (2004)) in NMP (10 mL) was added DIEA (374 mg, 2.9 mmol). The resulting mixture was stirred at 100° C. overnight. The reaction mixture was purified by preparative HPLC to give the desired product (212.2 mg, 0.69 mmol, yield 75%). 1H NMR (400 MHz, CDCl3) δ ppm 8.86 (brs, 1H), 8.12 (s, 1H), 5.53 (brs, 3H), 3.93-3.91 (m, 1H), 3.88-3.82 (m, 1H), 2.27-2.25 (m, 1H), 1.92-1.85 (m, 3H), 1.47 (s, 9H), 1.42-1.25 (m, 4H); MS (ESI) m/z=308.2 [M+1]+.
