Reaction Steps

17.4 g (0.10 mol) of 2-trifluoromethylphenylbenzaldehyde, 12.0 g (0.12 mol) of nitroacetone and 25.1 g (0.10 mol) of β-aminocrotonic acid 4-cyclohexylpiperazide are heated in 50 ml of isopropanol at 60° C. for 12 hours. On cooling, the product separates out and is recrystallized from isopropanol.
