実験手順

Compound from step 4 (213 mg, 1.00 mmol) and 2-chloro-6,7-dimethoxy-5-methyl-1H-quinazolin-4-one (254 mg, 1.00 mmol) were dissolved in dry DMSO. Et3N (0.14 mL, 1.00 mmol) was added, and the mixture was heated to 120° C. overnight. Upon cooling, the mixture was poured into water and extracted with diethyl ether. The ethereal extracts were dried over Na2SO4 and concentrated in vacuo. The residue was recrystallized from MeOH to give 54 mg (12.53%) of the above Example F-2 as a white crystalline powder. mp 191.0–193.5° C.; 1H NMR (DMSO-d6, 2.49) δ 2.59 (s, 3 H), 2.60 (s, 3 H), 3.03 (s, 3 H), 3.62 (s, 3 H), 3.84 (s, 3 H), 4.79 (s, 2 H), 5.02 (d, 1 H, J=10.6), 5.22 (d, 1 H, J=10.6), 6.64 (s, 1 H), 6.90 (d, 1 H, J=7.6), 7.01 (m, 2 H), 7.30 (t, 1 H, J=7.9); 13C NMR (DMSO-d6, 39.50) δ 13.90, 34.66, 35.59, 51.90, 55.93, 60.23, 84.92, 104.81, 108.46, 114.18, 115.02, 121.22, 130.13, 131.94, 140.10, 142.90, 150.63, 150.97, 157.71, 157.97, 163.67; MS (ES+) m/z 432 (M+H); Anal.
