Reaction Steps

A solution of 2,4-dichloro-8-methoxy-quinazoline (prepared as described in J. Chem. Soc. 1948, 1759) (0.6 g), N,N-diisopropyl-ethylamine (0.87 ml), and aniline (0.26 ml) in isopropanol (10 ml) is heated to reflux for 45 min. The cold reaction mixture is filtered and residue is crystallized from dichloromethane and hexanes to give 2-chloro-8-methoxy-4-phenylamino-quinazoline, m.p. 245-246° C.
