99%
Stage #1: for 1.5 h; Heating / reflux
Stage #2: With ammonia In methanol; water
4-(4-Bromo-2-fluorophenylamino)-6-methoxyquinazolin-7-ol Intermediate 2-3 (1.30 g, 2.86 mmol) was dissolved in trifluoroacetic acid (15 mL) and the solution was heated to reflux for 1.5 hours. The solution was cooled to room temperature and concentrated under reduced pressure. Methanol (20 mL) was added to the remaining brown solid and the pH was adjusted to 11 with concentrated ammonium hydroxide. The mixture was concentrated under reduced pressure and dried under high vacuum before purification by flash column chromatography on silica gel (20 g), eluting with 5-20percent methanol in dichloromethane. The experiment generated 2-4 (1.03 g, 99percent yield) as a light yellow solid.

A solution of 7-(Benzyloxy)-N-(4-bromo-2-fluorophenyl)-6-methoxyquinazolin-4-amine (3.5 g, 6.16 mmol, 1.00 equiv) and trifluoroacetic acid (30 mL) was heated at reflux for about 1 hour and then cooled to about 0° C.
The resulting solids were collected by filtration, and then dissolved in methanol (50 mL).
The pH value of the resulting solution was then adjusted to 9-10 with ammonium hydroxide (25percent).
