Reaction Steps

Proceeding as in Example 1, but substituting 2-(2H-1,2,3-triazol-2-yl)acetic acid and (2S,4R)—N-(4-(4-fluorophenoxy)phenyl)-4-(2,4,6-trifluorobenzyl)pyrrolidine-2-carboxamide, gave Compound 169, (2S,4R)-1-(2-(2H-1,2,3-triazol-2-yl)acetyl)-N-(4-(4-fluorophenoxy)phenyl)-4-(2,4,6-trifluorobenzyl)pyrrolidine-2-carboxamide. Major isomer: 1H-NMR (400 MHz, CDCl3): δ 9.12 (s, 1H), 7.72 (s, 2H), 7.43-7.38 (m, 2H), 7.03-6.86 (m, 6H), 6.72-6.64 (m, 2H), 5.12 (s, 2H), 4.82 (d, 1H), 3.63-3.57 (m, 1H), 3.22 (t, 1H), 2.92-2.74 (m, 3H), 2.59 (dd, 1H), 1.78-1.69 (m, 1H). MS (EI) for C28H23F4N5O3 found 554 (MH+).
