Reaction Steps

N-trifluoroacetyl-N-[bis(ethylamino)phosphinothioylmethyl]glycine, ethyl ester (2 g, 0.0055 mole), was dissolved in ethanol. The solution was stirred and sodium tetrahydrido boron (210 mg, 0.0055 mole) was added portionwise over a ten minute period. The solution was stirred for an additional 40 minutes. The solvent was removed by evaporation under vacuum and the residue was washed with water. The water washings were saturated with sodium chloride and the aqueous layer and insoluble residue were simultaneously extracted with ethyl acetate three times. The combined ethyl acetate extracts were dried over sodium sulfate, filtered and concentrated in vacuo. The resulting residue was then chromatographed on silica gel employing dichloromethane and then ether to yield N-[bis(ethylamino)phosphinothioylmethyl]glycine, ethyl ester (300 mg), ND25 =1.5128 and having the following analysis: Calculated: C, 40.44; H, 8.30; N, 15.72; P, 11.59; S, 11.99. Found: C, 40.19; H, 8.06; N, 15.37; P, 11.33; S, 11.74.
