Reaction Steps

To the solution of 4-(isopropylamino)-2-(methylsulfinyl)-pyrimidine-5-carboxamide and 4-(isopropylamino)-2-(methylsulfonyl)pyrimidine-5-carboxamide in NMP (from previous step, 2.8 mmol), 4-aminobicyclo[2.2.2]octan-1-ol hydrochloride (500 mg, 2.8 mmol), DIEA (1.1 g, 8.4 mmol) were added and heated at 100° C. for 3 d. The resulting mixture was concentrated under reduced pressure and the residue was purified by preparative thin layer chromatography to afford the final product (74.1 mg, 8.2% yield). 1H NMR (DMSO-d6) δ ppm 8.88 (br s, 1H), 8.31 (s, 1H), 7.5-6.5 (br s, 2H), 5.76 (s, 1H), 4:25 (s, 4.11 (brs, 1H), 2.05-1.97 (m, 6H), 1.61-1.54 (m, 6H), 1.24-1.12 (m, 6H); MS (ESI) m/z 320.2 [M+H]+; Purity=96.5% at 214 nm, Purity=97.7% at 254 nm.
