Reaction Steps
A solution of 116 mg (0.5 mmol) of 5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthoic acid, 58 mg (0.5 mmol) of ethyl 4-hydroxybenzoate, 117 mg (0.56 mmol) of 1,3-dicyclohexylcarbodiimide and 30 mg (0.25 mmol) of 4-dimethylaminopyridine in 15 ml of methylene chloride was stirred at room temperature for 12 hours. The reaction mixture was then filtered and the filtrate concentrated in-vacuo. The resultant residue was purified by flash chromatography (silica; 5% ethyl acetate in hexanes) to give the title compound as white crystals.
