Triethylamine → HCID 12928829, compound

Participants

Reaction Steps

To a solution of 3.3 g (0.02 mol) of 4-chloroquinazoline in 50 ml of benzene were added 2.0 g (0.02 mol) of triethylamine and 3.0 g (0.02 mol) of 2-benzyloxyethylamine, and the mixture was heated, with stirring, at 60°~70° C. for 5 hours. After completion of the reaction, the benzene was evaporated under reduced pressure, and the resulting crystals were washed with water, collected by filtration, dried and recrystallized from benzene/n-hexane, affording 3.7 g of 4-[2-(benzyloxy)ethyl]aminoquinazoline in the form of colorless needles.
