실험 절차

2-(3-Trifluoromethylbenzoyl)nicotinic acid (0.5 g), 4-trifluoromethylphenylhydrazine (0.3 g) and para-toluene sulphonic acid (0.001 g) were stirred in methanol at room temperature for 22 hours. Solvent was evaporated. The residue was triturated in cold toluene then dried to yield the title compound as a beige solid (0.62 g), m.p. 127°-129° C.
