Procedure

To a solution of ethyl-N-[(benzylthio)carbonyl]-N-[bis(phenoxy)phosphinylmethyl]-glycinate (1.0 g.; 0.002 mol.) dissolved in 10 ml. of methylene chloride at 0° C. was slowly added a solution of metachloroperbenzoic acid (0.4 g.; B 0.002 mol.) dissolved in 100 ml. of methylene chloride. The reaction mixture was stirred for one hour and allowed to gradually warm to 25° C. The mixture was washed with 5% sodium hydroxide, dried, then concentrated in vacuo. The resulting oil was extracted into hot petroleum ether and allowed to crystallize for 16 hours to yield ethyl-N-[(benzylsulfinyl)carbonyl]-N-[bis-(phenoxy)phosphinylmethyl]-glycinate as a solid having a melting point of 106°-115° C. and the folloing analysis:
