Procedure

Ethyl 2-(3-((4-(((tert-butoxycarbonyl)(methyl)amino)methyl)-2-(cyclohex-1-en-1-yl)-1H-pyrrol-1-yl)sulfonyl)phenoxy)acetate 8a (97 mg, 0.18 mmol) and lithium hydroxide (100 mg, 4.2 mmol) were added to 25 mL of a mixed solvent of tetrahydrofuran and water (V:V=1:1), and then the reaction solution was stirred for 1 h. The reaction solution was extracted with dichloromethane (50 mL×3), and the organic phases were combined, washed with saturated sodium chloride solution, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure to obtain the title product 2-(3-((4-(((tert-butoxycarbonyl)(methyl)amino)methyl)-2-(cyclohex-1-en-1-yl)-1H-pyrrol-1-yl)sulfonyl)phenoxy)acetic acid 8b (69 mg, a colorless oil) in 75% yield.
