Reaction Steps

2-(Adamantan-2-ylidene)-N-(2,4-dihydroxyphenyl)acetamide (formula VII) 3.0 g (adamantan-2-ylidene)acetic acid (formula R3COOH), 5.91 g triphenylphosphane and 4.95 g dipyridyldisulfide, dissolved in 100 ml of dichloromethane, are stirred at room temperature overnight. To the mixture obtained, 5.13 ml of N-ethyl-diisopropylamine and 4.83 g 2,4-dihydroxyaniline hydroxide (formula V) are added and the mixture is stirred for about 24 hours, the solvent is evaporated off, the evaporation residue is dissolved in ethyl acetate and extracted with a saturated aqueous NaH2PO4 solution and brine. The organic layer is dried, the solvent is evaporated off and the residue is purified by chromatography. The title compound is obtained (m.p. 166-169°).
