Reaction Steps

The title compound was prepared in an analogous manner as described for example 1h, starting from (1S,3R,4S,5S)-3-amino-5-[3-fluoro-4-nitro-5-((R)-2,2,2-trifluoro-1-methoxy-methyl-ethoxy)-benzyl]-1-oxo-tetrahydro-thiopyran-4-ol TFA salt (310 mg, 0.7 mmol) and 3-tert-butyl-benzaldehyde and was obtained after purification by flash-chromatography (hexane-(EtOAc-MeOH 9:1) gradient) as a light yellow foam: TLC (EtOAc-MeOH 9:1) Rf=0.38; HPLC RtH1=1.05 min; ESIMS [M+H]+=591; 1H NMR (600 MHz, CDCl3): δ 7.36 (s, 1H), 7.28 (s, 1H), 7.23 (m, 2H), 7.13 (d, 1H), 7.11 (d, 1H), 5.66 (m, 1H), 5.16 (d, 1H), 3.83-3.79 (m, 2H), 3.69 (dd, 1H), 3.63 (d, 1H), 3.55 (m, 1H), 3.30 (s, 3H), 3.14 (m, 2H), 3.00 (d, 1H), 2.55 (m, 1H), 2.5-2.4 (m, 3H), 1.95 (m, 1H), 1.25 (s, 9H).
