실험 절차

A mixture of 5-amino-6-chloro-N-[(1-isobutylpiperidin-4-yl)methyl]-2-methylimidazo[1,2-a]pyridine-8-carboxamide (EXAMPLE 26, Step 6, 134 mg, 0.36 mmol), 10% palladium charcoal (67 mg) and ammonium formate (224 mg, 3.6 mmol) in methanol (5 mL ) was stirred at room temperature for 4 h. The mixture was filtered through a pad of Celite and the filtrate was concentrated. The residue was treated with 25% aqueous ammonia (10 mL), extracted with dichloromethane (20 mL×2) and washed with brine (20 mL). Removal of the solvent gave 92.4 mg (0.37 mmol, 76%) of the title compound as a yellow amorphous.
