Procedure

A mixture of 3-(2-oxo-5,6-diphenyl-1,2,3,4-tetrahydropyrimidin-4-yl)benzonitrile (700 mg, 2 mmol, 1 eq), NH2OH—HCl (144 mg, 2.2 mmol, 1.1 eq) and Na2CO3 (414 mg, 4.0 mmol, 2.0 eq) in methanol (5.0 mL) was heated to reflux overnight. The mixture was cooled to room temperature and filtered. The filtered mass was washed with methanol (5.0 mL) and purified by prep-HPLC to afford Compound 99 as a yellow solid (150 mg, 19.5%) and Compound 98 as a white solid (6.7%). Data for Compound 99: 1H NMR (MeOH-d4 500 MHz TMS): δ 7.69-7.72 (m, 2H), 7.58-7.61 (m, 2H), 7.26 (br, 5H), 7.04 (br, 2H), 6.88 (br, 2H), 5.51 (s 1H); MS (ESI): m/z 385.1.1 [M+1]+.
