Reaction Steps

Proceeding as in Example 1, but substituting 2-(1H-1,2,4-triazol-1-yl)acetic acid hydrochloride and (2S,4R)—N-(4-(4-fluorophenoxy)phenyl)-4-(4-methylbenzyl)pyrrolidine-2-carboxamide, gave Compound 4, (2S,4R)-5-(2-(1H-1,2,4-triazol-1-yl)acetyl)-N-(4-(4-fluorophenoxy)phenyl)-4-(4-methylbenzyl)pyrrolidine-2-carboxamide. 1H-NMR (400 MHz, CDCl3): σ 9.02 (br s, 1H), 8.23 (s, 1H), 7.98 (s, 1H), 7.40 (m, 2H), 7.12 (d, 2H), 7.08 (d, 2H), 7.03-6.98 (m, 2H), 6.94-6.87 (m, 4H), 4.98 (dd, 2H), 4.78 (d, 1H), 3.62 (m, 1H), 3.23 (t, 1H), 3.02-2.87 (m, 2H), 2.65-2.60 (m, 2H), 2.34 (s, 3H), 1.74-1.66 (m, 1H); MS (EI) for C29H28FN5O3. found 514.1 (MH+).
