Procedure
To a suspension of (3R*,4S*,5S*)-3-(3-tert-butyl-benzylamino)-5-(3-fluoro-4-nitro-benzyl)-1,1-dioxo-hexahydro-1lambda*6*-thiopyran-4-ol (4.4 g, 8.7 mmol) in ACN was added at 25° C. the DIPEA and the carbonyl-diimidazole. After addition of a catalytic amount of DMAP, the clear reaction mixture was kept at 25° C. for 16 h. The reaction mixture was poured onto ice-water and acidified with 4N aq. HCl. The precipitate was filtered off and washed with H2O and Et2O, dried under reduced pressure for 6 h at 50° C. to yield the title product as light yellow crystals: TLC (toluene-THF 1:1) Rf=0.66; HPLC RtA=2.25 min; ESIMS [M+NH4]+=508; 1H NMR (400 MHz, DMSO-d6): δ 8.11 (dd, 1H), 7.48 (dd, 1H), 7.38 (s, 1H), 7.28 (m, 3H), 7.12 (d, 1H), 4.41 (d, 1H), 4.20 (m, 2H), 3.72 (m, 2H), 3.42 (dd, 1H), 3.14 (d, 2H), 3.04 (dd, 1H), 2.76 (dd, 1H), 2.64 (m, 1H), 1.25 (s, 9H).
