Procedure

To a mixture of 4-(bicyclo[1.1.1]pentan-1-ylamino)-2-(methylsulfinyl)pyrimidine-5-carboxamide, 4-(bicyclo[1.1.1]pentan-1-ylamino)-2-(methylsulfonyl)pyrimidine-5-carboxamide (300 mg) and tetrahydro-2H-pyran-4-amine hydrochloride (181.5 mg, 1.32 mmol) in NMP (10 mL) was added DIEA (426 mg, 3.3 mmol). The resulting mixture was stirred at 100° C. overnight. Then the reaction mixture was purified by preparative HPLC to give the desired product (221.3 mg, 0.73 mmol, yield 67%) as a yellow powder. 1H NMR (400 MHz, CD3OD) δ ppm 8.19 (s, 1H), 3.95-3.88 (m, 3H), 3.44-3.38 (m, 2H), 2.40 (s, 2.09 (s, 6H), 1.88-1.85 (m, 2H), 1.55-1.45 (m, 2H; MS (ESI) m/z=304.2 [M+1]+.
