Procedure

Freshly prepared ethyl-N-[(benzylthio)carbonyl]-N-[dichlorophosphinylmethyl]-glycinate (10.5 g.; 0.027 mol.) dissolved in 100 ml. of diethyl ether was added to a solution containing isopropylamine (6.7 g.; 0.11 mol.) in 50 ml. of diethyl ether. The reaction mixture was stirred for 2 hours at 25° C., then filtered. The filtrate was washed with 5% sodium bicarbonate, then water. The ether layer was separated, dried over sodium sulfate and concentrated in vacuo. To remove remaining traces of solvent, the residue was concentrated at 25° C. and 0.05 mm. and yielded ethyl-N-[(benzylthio)carbonyl]-N-[bis(isopropylamino)phosphinylmethyl]-glycinate (7.0 g.) as crystals having a melting point of 69°-72° C. and the following analysis:
