Procedure

To a solution of CDI (243 mg, 1.50 mmol) in THF (3 mL) was added 4-(3-amino-5-ethoxy-4-hydroxyphenyl)-5,6-diphenyl-3,4-dihydropyrimidin-2(1H)-one (386 mg, 0.96 mmol) and the resultant mixture was heated to reflux for 1.0 h. The reaction mixture was added water (10 mL) and filtered. The filtered mass was washed with methanol (3 mL) and dried to afford Compound 72 as a yellow solid (110 mg, 30%). 1H NMR (DMSO-d6 500 MHz): δ 11.56 (s, 1H), 8.69 (s, 1H), 7.49 (s, 1H), 7.21 (s, 3H), 7.20 (s, 2H), 6.99-7.04 (m, 3H), 6.81 (d, J=6.0 Hz, 2H), 6.74 (d, J=6.0 Hz, 2H), 5.12 (s, 1H), 4.11 (q, J=6.8 Hz, 2H), 1.31 (t, J=7.0 Hz, 3H); MS (ESI): m/z 428.1 [M+1]+.
