Versuchsvorschrift
Procedure HH: To a stirring solution of 3′-Methanesulfonyl-biphenyl-4-carboxylic acid methyl ester (1.0 mmol) in 1:1 methanol/tetrahydrofuran (0.15M), add 2N sodium hydroxide (3.0 mmol) and heat to reflux for 1 hour. After this time, remove the heat and concentrate in vacuo. Wash with 1N hydrochloric acid and water while extracting with 10% isopropanol/dichloromethane. Concentrate the organic layer in vacuo to yield the title compound. MS (m/e): 275.1 (M−1)
