実験手順

To a solution of pivalic acid 6-{2-{ethyl[4-(8-methyl-8-azabicyclo[3.2.1 ]oct-3-yloxy)benzyl]amino}-4-methoxyphenyl}-5,6,7,8-tetrahydronaphthalen-2-yl ester (19 mg) in ethanol (1 ml) was added an aqueous solution of 1N sodium hydroxide (0.2 ml), and the solution was stirred for 1.5 hours at 60° C. The solution was neutralized with 1N hydrochloric acid, extracted with ethyl acetate, then sequentially washed with water and brine, dried over anhydrous magnesium sulfate, and then the solvent was evaporated in vacuo. The residue was purified by NH silica gel column chromatography (ethyl acetate-methanol system) to provide the title compound (12 mg).
