실험 절차

(R)-8-Benzyloxy-5-[2-(4,7-dimethoxy-indan-2-ylamino)-1-hydroxy-ethyl]-1H-quinolin-2-one (37 mg, 0.08 mmol) is dissolved in methanol (10 mL) and the compound is deprotected by adding a catalytic amount of 10% palladium on charcoal and placing the solution under an atmosphere of hydrogen. The reaction is shown to be complete by TLC after 4 hours. The catalyst is filtered off, 1M HCl/diethyl ether (1.1 equivalent) is added and the solvent is removed in vacuo. TLC (silica, dichloromethane/methanol 10:1 Rf=0.15). ES+ MS m/e 397 (MH+).
