Reaction Steps

Prepared as previously described in Example 71 using (S)-1-((R)-2-(3-azidopropyl)-5-(2,5-difluorophenyl)-2-phenyl-1,3,4-thiadiazol-3(2H)-yl)-2-(tert-butyldiphenylsilyloxy)propan-1-one from Step C. MS ESI (+) m/z 420 (M+1) detected; 1H NMR (400 MHz, CDCl3) δ 7.51 (m, 1H), 7.44 (m, 2H), 7.36 (m, 2H), 7.29 (m, 1H), 7.12 (m, 2H), 4.71 (q, 1H, J=6 Hz), 3.32 (s, 3H), 3.23 (m, 1H), 2.84 (m, 2H), 2.43 (m, 1H), 1.93 (m, 1H), 1.50 (d, 3H, J=6 Hz), 1.44 (m, 2H), 1.34 (m, 1H). Stereochemistry was assigned by inference from (S)-1-((S)-2-(3-aminopropyl)-5-(2,5-difluorophenyl)-2-phenyl-1,3,4-thiadiazol-3(2H)-yl)-2-methoxypropan-1-one.
