Tetrabutylammonium Fluoride → HCID 57443542, compound

Participants

Reaction Steps

Tetrabutylammonium fluoride (1 M solution in tetrahydrofuran, 0.316 mL, 0.316 mmol) was added to a solution of [5-(4-{1-ethyl-1-[4-(3-ethyl-3-trimethylsilanyloxy-1-pentynyl)-3-methyl-phenyl]-propyl}-2-methyl-phenyl)-pyridin-3-yl]-acetic acid methyl ester (Example 151-(1); 36.9 mg, 0.063 mmol) in tetrahydrofuran (3 mL), and the mixture was stirred at room temperature for 30 minutes. Then, the reaction mixture was diluted with ethyl acetate and was washed with brine. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The resulting residue was purified by silica gel chromatography (hexane:ethyl acetate=1:1) to give the target compound as a colorless oil (16.7 mg, 52%).
