Procedure
Into a mixture of 600 ml. of tetrahydrofuran, 45.8 g. of hydroxyethyl acrylate, and 72 g. of 3-(2-chloroethylsulfonyl)propionyl chloride placed in a reaction vessel chilled with ice-water to maintain the temperature below 5° C., a solution of 31.2 g. of pyridine in 100 ml. of tetrahydrofuran was poured dropwise for 1.75 hours. The resulting mixture was stirred at room temperature for 2 hours, and poured into 2.5 l. of ice-water. The aqueous mixture was then extracted with 4 portions of 300 ml. of chloroform. The organic extract was dried over sodium sulfate, and concentrated to give 87 g. of 2-[3-(2-chloroethylsulfonyl)propionyloxy]ethyl acrylate (yield 88%).
