2-(Bicyclo[1.1.1]pentan-1-ylamino)-4-((1R,3R,4R)-3-hydroxy-4-methylcyclohexylamino)pyrimidine-5-carbonitrile (0.38 g, 1.213 mmol) was dissolved in DMSO (26.9 mL) and to this solution was added a 50% aqueous sodium hydroxide solution (0.097 ml, 1.213 mmol) and a 30% aqueous hydrogen peroxide solution 0.137 mL, 1.213 mmol) at room temperature. Then the reaction mixture was stirred at 50° C. for 1 h. The reaction was cooled to room temperature and it was poured into 50 mL of ice water. The white precipitate was collected on filter paper and was washed twice with water. The precipitate was dried to give 2-(bicyclo[1.1.1]pentan-1-ylamino)-4-((1R,3R,4R)-3-hydroxy-4-methylcyclohexylamino)-pyrimidine-5-carboxamide (0.269 g, 0.812 mmol, 67% yield). 1H NMR (DMSO-d6, 400 MHz): δ ppm 0.94 (d, J=6.25 Hz, 3H) 1.10-1.26 (m, 3H) 1.68 (d, J=10.54 Hz, 1H) 1.92 (d, J=10.93 Hz, 1H) 2.06 (s, 6H) 2.17 (d, J=9.76 Hz, 1H) 2.46 (s, 1H) 2.98 (br. s., 1H) 3.82-3.95 (m, 1H) 4.63 (br. s., 1H) 7.16 (br. s., 1H) 7.77 (br. s., 1H) 8.11 (br. s., 1H) 8.33 (s, 1H) 9.24 (br. s., 1H); MS (ESI): m/z 332.3 [M+1]+.
