Reaction Steps

To a solution of 2.5 g (0.015 mol) of 4-chloroquinazoline in 50 ml of benzene were added 1.5 g (0.015 mol) of triethylamine and 3.5 g (0.015 mol) of 2-(p-bromophenylthio) ethylamine, and the mixture was heated, with stirring, at 70°~80° C. for 3 hours. After completion of the reaction, the benzene was evaporated under reduced pressure and the resulting crystals were washed with water, collected by filtration and recrystallized from ethanol, giving 3.0 g of 4-[2-(4-bromophenylthio)ethyl]aminoquinazoline in the form of colorless granules.
