Reaction Steps

A solution of 2,4-dichloro-quinazoline (15 g) N,N-diisopropyl-ethylamine (24.9 ml) and aniline (7.5 ml) in isopropanol (75 ml) is heated to reflux for 45 min. The cold reaction mixture is filtered and the filtrate is concentrated in vacuo. The residue is crystallized from diethylether-toluene (1:1) to give 2-chloro-4-phenylamino-quinazoline, m.p. 194-196° C.
