Procedure
The product from Step A (200 mg) was dissolved in 1.5 ml of DMSO and was added rapidly dropwise to a solution of 200 mg of NaBH4 in 5 ml of 95% ethanol. After 30 minutes, the mixture was poured into dilute HCl and extracted with ethyl acetate. The extract was washed with water, and brine and dried (Na2SO4) and evaporated to dryness. The residue was pure by TLC and the structure was not contraindicated by 'H-NMR. Mass spectrum shows m/e=277. Calc'd for C9H11NO5S2 : C, 38.98; N, 5.05; H, 4.00%. Found: C, 39.34; N, 5.15; H, 3.95%.
