Procedure
To a solution of 2,4-dichloro-quinazoline obtained in step B of example 1 (4 g, 20 mmol) in THF (50 mL) were added tert-butyl amine (2.15 mL, 20.5 mmol) and diisopropylethylamine (3.5 mL, 21 mmol). The mixture was stirred at ambient temperature for 2 hr. The mixture was concentrated and the residue was dissolved in EtOAc. The organic layer was washed with water, dried over Na2SO4, and filtered. The mixture was concentrated to give tert-butyl-(2-chloro-quinazolin-4-yl)-amine as a white solid (3 g, 64%).
