실험 절차

To a degassed solution of ethyl 4-[1(tol-4-yl)3,4-dihydro-4,4-dimethyl-anthracen-8-yl]-benzoate (Compound 1, 35 mg, 0.08 mmol), in THF (1.5 mL) and MeOH (1.5 mL) was added LiOH (1M solution in water, 0.3 mL, 0.3 mmol). The mixture was stirred at ambient temperature for 16 hours, diluted with ether (60 mL). The mixture was acidified with 10% HCl to pH 4, the product was isolated as an ether insoluble white solid.
