Reaction Steps

A mixture of (E)-3-{2-[4-(1-amino-cyclobutyl)-phenyl]-3-phenyl-imidazo[1,2-a]pyridin-7-yl}-acrylamide (111 mg, 0.27 mmol) and 10% palladium on carbon (14 mg) in MeOH (10 mL) was stirred under a hydrogen atmosphere for 23 h, additional palladium on carbon (14 mg) was added and the reaction was stirred under a hydrogen atmosphere for 6 h. The resulting mixture was filtered. The resulting solution was concentrated under reduced pressure. The remaining material was purified using MPLC (Biotage Isolera Flash NH2 Snap 10 reverse phase column; 100% CH2Cl2 for 8 min., gradient to 95% CH2Cl2: 5% MeOH over 5 min.; 95% CH2Cl2: 5% MeOH for 4 min., gradient to 80% CH2Cl2: 20% MeOH over 5 min., 80% CH2Cl2: 20% MeOH for 6.2 min.) to give 3-{2-[4-(1-amino-cyclobutyl)-phenyl]-3-phenyl-imidazo[1,2-a]pyridin-7-yl}-propionamide (24 mg, 17%):
