実験手順

Triphenylphosphine (11.4 g) was added portionwise to a stirred solution of 5-chloro-2-methoxybenzenesulphonyl chloride (3.0 g) in THF (30 ml). Water (4 ml) was added and the mixture stirred at RT for 2 h, afterwhich the reaction was diluted with water (25 ml) then 2M sodium hydroxide solution and washed with ether. The aqueous layer was acidified with 2M hydrochloric acid and extracted with ethylacetate. The organic layer was dried and evaporated under reduced pressure, yield 3.1 g.
