Reaction Steps

Proceeding as in Example 1, but substituting 2-(4-methyl-1,2,3-triazol-1-yl)acetic acid hydrochloride and (S)-2-amino-3-(benzyloxy)-N-(4-(4-fluorophenoxy)phenyl)propanamide, gave Compound 153, (S)-3-(benzyloxy)-N-(4-(4-fluorophenoxy)phenyl)-2-(2-(4-methyl-1H-1,2,3-triazol-1-yl)acetamido)propanamide (13 mg, 18%); Major isomer: 1H-NMR (400 MHz, DMSO-D6): σ 10.24 (br s, 1H), 8.84-8.82 (d, 1H), 7.76 (s, 2H), 7.63-7.59 (d, 2H), 7.32-7.27 (m, 5H), 7.23-7.19 (t, 2H), 7.04-6.98 (m, 4H), 5.15 (s, 1H), 4.75-4.70 (m, 1H), 4.54 (s, 2H), 3.70-3.68 (d, 2H), 2.23 (s, 3H). MS (EI) for C27H26FN5O4. found 504.0 (MH+).
