実験手順

A mixture of the 4-[5-methoxy-4-piperidin-1-yl-2-(3,3,5,5-tetramethylcyclohexyl)phenyl]piperazine-1-carboxylic acid t-butyl ester (88 mg, 0.17 mmol) produced in Example (72a), trifluoroacetic acid (0.25 mL, 3.2 mmol) and dichloromethane (0.5 mL) was stirred for 1 hour and 10 minutes at room temperature. Saturated aqueous solution of sodium hydrogencarbonate was added to the reaction mixture and extraction was performed with ethyl acetate. The separated organic layer was dried over anhydrous sodium sulfate. The desiccant was filtered off and the filtrate was concentrated under reduced pressure. The resultant residue was purified by NH silica gel column chromatography (ethyl acetate/heptane) to give 56 mg of the title compound as a red solid.
