Reaction Steps

Proceeding as in Example 1, but substituting 2-(1H-1,2,3-triazol-1-yl)acetic acid and (2S,4R)—N-(4-(4-fluorophenoxy)phenyl)-4-(2,4,6-trifluorobenzyl)pyrrolidine-2-carboxamide, gave Compound 170, (2S,4R)-1-(2-(1H-1,2,3-triazol-1-yl)acetyl)-N-(4-(4-fluorophenoxy)phenyl)-4-(2,4,6-trifluorobenzyl)pyrrolidine-2-carboxamide. Major isomer: 1H-NMR (400 MHz, CDCl3): δ 8.93 (s, 1H), 7.80-7.74 (m, 2H), 7.44-7.38 (m, 2H), 7.03-6.85 (m, 6H), 6.74-6.62 (m, 2H), 5.31 (d, 1H), 5.20 (d, 1H), 4.76 (d, 1H), 3.79-3.73 (m, 1H), 3.34 (t, 1H), 2.98-2.76 (m, 3H), 2.55 (dd, 1H), 1.83-1.74 (m, 1H). MS (EI) for C28H23F4N5O3 found 554 (MH+).
