Procedure

4-Chloro-3-(2-chloroethyl)cinnoline (1 g, 0.0044 mol) and 4-hydroxy-2-methylphenylamine (0.54 g, 0.0044 mol) in 1,4 dioxan (20 ml) were heated under reflux for 20 hours. The solid obtained was collected by filtration and dried. Recrystallization from ethanol gave the title compound, 0.4 g, m.p. >300°
