Reaction Steps

A solution of 4-chloro-7-nitroquinazoline hydrochloride (2.46 g, 10 mmol) and 2-fluoro-5-methoxycarbonyloxy-4-methylaniline (2.2 g, 11 mmol), (prepared as described for the starting material in Example 12), in isopropanol (25 ml) was heated at 50° C. for 1 hour. The mixture was allowed to cool, the precipitated solid was collected by filtration recrystallised from methylene chloride/methanol/isopropanol to give 4-(2-fluoro-5-methoxycarbonyloxy-4-methylanilino)-7-nitroquinazoline hydrochloride (1.8 g, 45%) as a yellow solid.
