Versuchsvorschrift
4-Chloro-2-(difluoro(4-fluorophenyl)methyl)-7-methoxyquinazoline was obtained according to the procedure described in Example 26 for synthesis of 4-chloro-2-(difluoro(4-fluorophenyl)methyl)-7-methylquinazoline, substituting 2-(difluoro(4-fluorophenyl)methyl)-7-methylquinazolin-4-ol in Example 26 with 2-(difluoro(4-fluorophenyl)methyl)-7-methoxyquinazolin-4-ol. 4-Chloro-2-(difluoro(4-fluorophenyl)methyl)-7-methoxyquinazoline was isolated as a light yellow solid (0.290 g, 89%). LC-MS (ESI) m/z 339 (M+H)+.
