Reaction Steps
A solution of 3-amino-1-(3-trifluoromethylphenyl)-2-pyrazoline (2.29 g) and salicylaldehyde (1.2 g) in methanol (22.9 ml) was heated to reflux for 30 minutes. The resulting semi-solid mass was cooled and then filtered to give an orange-coloured solid which was re-crystallized from ethanol to produce 3-salicylideneamino-1-(3-trifluoromethylphenyl)-2-pyrazoline m.p. 159.1° (yield 1.7 g).
