Procedure

A solution of 4.63 g of 2-chloro-6-methylbenzenesulfonyl chloride dissolved in 20 ml of anhydrous ether was added dropwise over a 15 minute period to a mixture of 3.50 g of diethyl P-(hydroxymethyl)phosphonate (Example 17), 5 ml of triethylamine and 15 ml of anhydrous ether. The addition was mildly exothermic and a white precipitate began to form shortly after the addition of the sulfonyl chloride was begun. The reaction was stirred at room temperature overnight. After 48 hours of additional stirring the reaction solution was diluted with 200 ml of ethyl acetate and 80 ml of water. The organic phase was washed with two 90 ml portions of water, dried with magnesium sulfate, filtered and concentrated to yield 6.4 g of an oil which solidified upon standing, mp 41°-43° C.
