Reaction Steps
This compound was obtained by reacting rac-3,4-dihydro-2-ethynyl-2,5,7,8-tetramethyl-2H-1-benzopyran-6-ol with 2-iodoaniline under the conditions described in Example 26. The product was isolated by chromatography over the 40 fold amount of silica gel using methylene chloride. Crystallization from ether/hexane and recrystallization from cyclohexane gave pale yellow crystals with m.p. 110°-112°.
