実験手順

Trifluoroacetic acid (0.03 mL) was added to a solution of {6-[4-(1-{4-[3-(t-butyl-dimethyl-silanyloxy)-4,4-dimethyl-pentyl]-3-methyl-phenyl}-1-ethyl-propyl)-2-methyl-phenyl]-pyridin-3-yl}-acetic acid ethyl ester (Example 23-(2); 2.1 mg, 0.0033 mmol) in dichloromethane (0.15 mL) at room temperature, and the mixture was stirred at room temperature for one hour and 15 minutes. The solvent in the reaction solution was distilled off under reduced pressure. The residue was purified by silica gel chromatography (hexane/ethyl acetate=3/1) to give the title compound (1.7 mg, 100%).
