Temperature: 70 °C

Procedure

(3-Chloro-4-fluoro-phenyl)-(7-fluoro-6-nitro-quinazolin-4-yl)-amine was suspended in 100 ml methanol and 2 ml 50% NaOH in water was added and the mixture was heated at 70° C. for 2 hours. The mixture was then poured into water and stirred vigorously for 30 minutes, then filtered and washed with water and dried under vacuum at 60° C. overnight to give 7.2 g of (3-Chloro-4-fluoro-phenyl)-(7-methoxy-6-nitro-quinazolin-4-yl)-amine.
