Reaction Steps

To a stirring solution of 2-(bicyclo[1.1.1]pentan-1-ylamino)-4-(methylthio)pyrimidine-5-carbonitrile (566 mg, 2.436 mmol) in DMSO (7 mL) was added 6 M aqueous sodium hydroxide solution (2.030 mL, 12.18 mmol) and 30% aqueous hydrogen peroxide solution (1.381 mL, 12.18 mmol) at 0° C. The mixture was then stirred at 50° C. for 30 min and then was poured into ice water (50 mL). The solids that formed were stirred in an ice bath for 30 min, filtered, washed with water, and then dried in a vacuum oven overnight at 45° C. to afford 2-(bicyclo[1.1.1]pentan-1-ylamino)-4-(methylthio)pyrimidine-5-carboxamide (410 mg, 1.638 mmol, 67.2% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.41 (s, 1H), 7.03-8.34 (m, 2H), 2.43-2.48 (m, 1H), 2.35 (br. s., 3H), 2.09 (s, 6H). MS (ESI) m/z 251.3 [M+1]+.
