Reaction Steps

The procedure used was the same as for N-(3-(4-arsenosophenylcarbamoylmethylthio)propanoyl)-L-aspartic acid, using 2.63 mL (184 μmol) of 70.0 mM BRAO in DMSO, the disulfide of disodium N-(3-mercaptopropanoyl)-L-glutamate (0.61 g), 0.5 M bicarbonate buffer, pH 9 (10.52 mL, 5.3 mmol), and 0.69 M triphenylphosphine in DMSO (1.7 mL, 1.2 mmol). In this case, DMSO (2 mL) was added to the precipitated mixture before leaving overnight. The active concentration of trivalent arsenic was found to be 15.4 mM (10.3 mL of solution).
