반응 단계

This compound was prepared in the manner of Example II, using 5.3 g of 2-(4-chlorophenyl)-3-methylbutanoyl chloride, whose preparation is described in Agr. Biol. Chem., 38, 881 (1974), together with J. Kagaku To Seibutsu, 14, 427 (1976), 4.6 g of α-trifluoromethyl-3-phenoxybenzyl alcohol, and 1.5 g of pyridine in 50 ml of toluene. Volatiles were removed from the crude reaction product at 100° C./0.02 mm through a short path Kugelrohr distillation system to give as a residue 7.8 g of α-trifluoromethyl-3-phenoxybenzyl 2-(4-chlorophenyl)-3-methylbutanoate. The ir spectrum was consistent with the assigned structure.
