Procedure
Starting material: N4-(3-chloro-2,4-difluorophenyl)-7-methoxyquinazoline-4,6-diamine was prepared according to the same method of preparation of N4-(3-chloro-4-fluorophenyl)-7-(2-methoxy)ethoxyquinazoline-4,6-diamine in WO2008/33747, but the starting materials were 4-chloro-7-methoxy-6-nitro-quinazoline and 3-chloro-2,4-difluoro-aniline; other starting materials were prepared as example 1.
Workup
- customother starting materials were prepared as example 1
