実験手順

To a mixture of 3-(4-amino-2-methylphenyl)-2,3,4,7-tetrahydro-6H-pyrimido[1,2-c]quinazolin-6-one (92 mg, 0.30 mmol) and triethylamine (0.125 mL, 0.90 mmol) in 2.5 mL CH2Cl2 at rt was added 2-fluoro-5-(trifluoromethyl)phenyl isocyanate (0.065 mL, 0.45 mmol) and the reaction stirred at rt. After 2.5 hours the reaction was quenched with 0.3 mL MeOH, and then stored overnight in the refrigerator. The reaction mixture was filtered and rinsed with EtOAc to give the title compound as an off-white solid (130 mg, 84%). 1H NMR (DMSO-d6) δ: 10.69 (s, 1H), 9.09 (s, 1H), 8.87 (d, J=2.9 Hz, 1H), 8.63 (dd, J=7.5, 2.2 Hz, 1H), 7.99 (dd, J=7.9, 1.2 Hz, 1H), 7.33-7.53 (m, 4H), 7.24-7.29 (m, 1H), 7.13-7.17 (m, 1H), 7.00-7.10 (m, 2H), 4.15-4.23 (m, 1H), 3.64-3.73 (m, 1H), 3.46-3.56 (m, 2H), 3.07-3.15 (m, 1H), 2.33 (s, 3H)
