実験手順

A stirred solution of 3-(3-chloro[1,1'biphenyl]-2-yl)-1-propanol (30.0 g, 0.12 mole) and pyridine (11.9 g, 0.15 mole) in methylene chloride (300 ml) was cooled to 0°. Methanesulfonyl chloride (13.9 g, 0.12 mole) was added dropwise to the mixture. After complete addition the mixture was allowed to warm to room temperature and stir for approximately 18 hours. The reaction mixture was diluted with ice water (50 grams) and washed successively with dilute hydrochloric acid (200 ml), saturated aqueous sodium chloride (700 ml) and dilute aqueous sodium hydroxide (200 ml). The organic phase was dried over anhydrous magnesium sulfate, filtered and the filtrate evaporated under reduced pressure to yield (3-chloro[1,1'-biphenyl]-2-yl)propanyl methylsulfonate as a brown oil.
