실험 절차

A solution of methyl 2,6-difluoro-4-[(3-methoxymethoxy-5,5,8,8,-tetramethyl-5,6,7,8-tetrahydro-naphthalene-2-carbonyl)-amino]-benzoate (Compound A, 113 mg, 0.26 mmol) in 6 ml of methanol and 3 drops of conc. HCl was stirred at room temperature for overnight and then concentrated to dryness. The solid was recrystallized from ethyl ether: hexane to give the title compound as a white solid.
