A slurry of palladium 10% on carbon, 50% water (0.26 g), methyl 1-(4-(5-(1-(4-(benzyloxy)phenyl)cyclopropyl)thiazolo[5,4-b]pyridine-2-yl)-3-fluorobenzyl)azetidine-3-carboxylate (0.144 g, 0.25 mmol), triethylamine (0.087 mL, 0.62 mmol) in 4 mL of 3:1 THF/MeOH was stirred rapidly under an atmosphere of hydrogen (balloon) for 36 h. The reaction mixture was diluted with DCM, and filtered through celite and concentrated in vacuo. The resulting solid was adsorbed onto 1.4 g silica gel and purified by silica gel chromatography 0-100% EA/hexanes, to give methyl 1-((3-fluoro-4-(5-(1-(4-hydroxyphenyl)cyclopropyl)thiazolo[5,4-b]pyridine-2-yl)phenyl)methyl)-azetidine-3-carboxylate as a white solid. MS (ESI) m/z: calculated: 489.2; Observed: 490.1 (M++1).
