반응 단계
2-Ethyl-7-hydroxy-2-methyl-4-chromanone, m.p. 109°-110.5° C., was prepared by condensing resorcinol with 3-methyl-2-pentanoic acid in the presence of boron trifluoride diethyl etherate. Reaction of the chromanone with 3-trifluoromethylphenyl magnesium bromide as described in Preparation 5 gave the title chromene as a golden yellow oil.
