실험 절차

4-Trifluoromethylphenylisocyanate (2.55 g, 0.0136 mole) was added to the amine ((g), 6.56 g, 0.0136 mole) in THF (ml 100). After 1 hour stirring, the solution was evaporated to dryness and the residue crystallized from toluene to give the coupler ((h), 6 g, 67%) as white prisms. The product structure was confirmed by NMR analysis.
