Reaction Steps

A flask was charged with (S)-2-(2-(1H-imidazol-4-yl)acetamido)-3-(benzyloxy)-N-(4-(5-bromothiazol-2-yloxy)phenyl)propanamide (25 mg, 0.045 mmol), prepared as in Example 1, methanol (20 mL), ammonium formate (300 mg, 4.84 mmol), and palladium on carbon (10%, 100 mg) and the mixture was heated at 70° C. for 30 minutes. The mixture then was cooled to ambient temperature and filtered. Product was purified from the residue by chromatography (EtOAc to EtOAc/MeOH (9:1)) and then further purified by reverse phase HPLC to provide Compound 206, (S)-2-(2-(1H-imidazol-4-yl)acetamido)-3-(benzyloxy)-N-(4-(thiazol-2-yloxy)phenyl)propanamide (10.6 mg, 51%), as an off-white solid. 1H-NMR (400 MHz, DMSO-d6): 10.35 (s, 1H), 8.43 (d, J=6.4 Hz, 1H), 7.68 (d, J=11.2 Hz, 2H), 7.60 (s, 1H), 7.31-7.23 (m, 8H), 6.95 (s, 1H), 4.70-4.64 (m, 1H), 4.49 (s, 2H), 4.14-4.09 (m, 2H), 3.69-3.63 (m, 2H). MS (EI) for C24H23N5O4S. found 478.2 (MH+).
