Reaction Steps

To a mixture of 5-[(1-benzylpiperidin-4-yl)amino]-6-ethyl-3-({3-methyl-4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}amino)pyrazine-2-carboxamide (Example 507) (1.31 g), ethanol (26 mL) and acetic acid (13 mL), palladium hydroxide (0.65 g) was added and stirred under a hydrogen atmosphere at room temperature for 3 days. After the catalyst was separated by filtration, the solvent was concentrated and partitioned using chloroform and saturated aqueous sodium hydrogen carbonate. The organic layer was concentrated to give 6-ethyl-3-({3-methyl-4-[4-(4-methylpiperazin-1-yl)piperidin-1-yl]phenyl}amino)-5-(piperidin-4-ylamino)pyrazine-2-carboxamide (0.73 g) as a light yellow solid.
