Reaction Steps

A solution of tert-butyl{(2R)-1-{[tert-butyl(diphenyl)silyl]oxy}-3-[(3-nitro-2-oxo-1,2-dihydropyridin-4-yl)sulfanyl]propan-2-yl}carbamate (44, 507 mg, 0.87 mmol) and ammonium acetate (1.1 g, 14.0 mmol) in THF (12 ml) and water (3 ml) was treated with anhydrous tin(II) chloride (1.04 g, 5.5 mmol) and the mixture stirred at +65° C. for 22 h. The reaction mixture was diluted with DCM, washed with saturated NaHCO3, dried over MgSO4, filtered and concentrated. Purification was performed in a chromatographic column on silicagel, eluted with 30% to 100% EtOAc in hexane to afford title compound (303 mg, 63% yield) as a light green solid. MS: m/z=576.2 (MNa+).
