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).
