Reaction Steps

The title compound can be prepared in an analogous manner as described for example 41 steps c) and d) from (1R,3R,4S,5S)-3-amino-5-[3-fluoro-4-nitro-5-((R)-2,2,2-trifluoro-1-methoxymethyl-ethoxy)-benzyl]-1-oxo-tetrahydro-thiopyran-4-ol hydrochloride and 5-(2,2-dimethyl-propyl)-isoxazole-3-carbaldehyde and subsequent transformation into the hydrochloride salt with 5N HCl in Et2O to afford the title compound as a beige foam: TLC (CH2Cl2-MeOH 9:1) Rf=0.53; HPLC RtG3=1.77 min; ESIMS [M+H]+=566; 1H NMR (400 MHz, DMSO-d6): δ 6.73 (s, 1H), 6.64 (d, 1H), 6.25 (s, 1H), 5.12-5.06 (m, 1H), 4.99 (d, 1H), 4.59 (s, 2H), 3.83-3.68 (m, 4H), 3.33 (s, 3H), 3.17-3.06 (m, 3H), 3.00-2.97 (m, 1H), 2.72-2.68 (m, 1H), 2.63 (s, 2H), 2.45-2.27 (m, 4H), 0.93 (s, 9H).
