Procedure

A mixture of 3-formyl-1-phenyl-2-pyrazoline (3.48 g), n-butylamine (0.2 ml) and nitromethane (10 ml) was stirred at 100° C. for 1 hour, then was cooled to room temperature. The resultant dark red crystalline mass was dissolved in toluene and was eluted down a silica column with toluene. The major orange fraction was evaporated to dryness under reduced pressure and the residue was recrystallised from ethanol to give a 59% yield of dark red micro crystals (MP 150° C.).
