Reaction Steps

To a solution of {(3R,4S,5S)-5-[3-fluoro-4-nitro-5-(2,2,2-trifluoro-1-trifluoromethyl-ethoxy)-benzyl]-4-hydroxy-1,1-dioxo-hexahydro-1lambda*6*-thiopyran-3-yl}-carbamic acid tert-butyl ester (3.42 g, 5.85 mmol) in THF (5 mL) was added 4N HCl in dioxane (20 mL) and the reaction mixture was stirred for 2 h at 25° C. After evaporation the residue was stirred with Et2O, filtered and dried to provide the title compound as a beige solid: TLC (EtOAc-MeOH 9:1) Rf=0.12; HPLC RtA=1.76 min; ESIMS [M+H]+=485; 1H NMR (400 MHz, CD3OD): δ 7.24 (s, 1H), 7.18 (d, 1H), 6.29 (m, 1H), 3.3-3.7 (m, 5H), 3.21 (dd, 1H), 2.97 (m, 1H), 2.70 (dd, 1H), 2.42 (m, 1H).
