Participants

Reaction Steps

2-(Difluoro(4-fluorophenyl)methyl)-7-methoxyquinazolin-4-ol was prepared according to the procedure described in Example 20 for preparation of 2-(difluoro(4-fluorophenyl)-7-fluoroquinazolin-4-ol, substituting 2-(2,2-difluoro-2-(4-fluorophenyl)acetamido)-4-fluorobenzamide in Example 20 with 2-(2,2-difluoro-2-(4-fluorophenyl)acetamido)-4-methoxybenzamide. The crude product (˜100% yield) was taken directly to the next step. 1H NMR (300 MHz, DMSO-d6) δ 3.89 (s, 3H), 7.16 (m, 2H), 7.39 (t, 2H), 7.75 (m, 2H), 8.04 (d, 1H), 12.96 (s, 1H); LC-MS (ESI) m/z 321 (M+H)+.
