Reaction Steps

Proceeding as in Example 1, but substituting 2-(2H-1,2,3-triazol-2-yl)acetic acidhydrochloride and (2S,4R)-4-(2-chloro-4-fluorobenzyl)-N-(4-(4-fluorophenoxy)phenyl)pyrrolidine-2-carboxamide, gave Compound 5, (2S,4R)-1-(2-(2H-1,2,3-triazol-2-yl)acetyl)-4-(2-chloro-4-fluorobenzyl)-N-(4-(4-fluorophenoxy)phenyl)pyrrolidine-2-carboxamide. 1H-NMR (400 MHz, CDCl3): δ 9.15 (s, 1H), 7.70 (s, 2H), 7.40-7.36 (m, 2H), 7.23-7.12 (m, 2H), 7.02-6.84 (m, 7H), 5.31 (s, 2H), 4.80 (d, 1H), 3.62-3.57 (m, 1H), 3.24 (t, 1H), 3.04-2.95 (m, 1H), 2.90-2.85 (m, 1H), 2.53 (dd, 1H), 1.79-1.70 (m, 1H). MS (EI) for C28H25ClF2N5O3 found 552 (MH+).
