Reaction Steps

To a mixture of 5-[(trans-4-hydroxycyclohexyl)amino]-6-isopropenyl-3-{[4-(4-methylpiperazin-1-yl)phenyl]amino}pyrazine-2-carboxamide (Example 342) (205 mg), ethanol (20 mL) and THF (10 mL), 10% palladium on carbon (100 mg) was added under a hydrogen atmosphere and stirred at room temperature for 18 hours. After the catalyst was separated by filtration, the solvent was distilled off, and the residue was purified by basic silica gel column chromatography (eluent: chloroform). The resulting yellow solid was washed with ethyl acetate to give 5-[(trans-4-hydroxycyclohexyl)amino]-6-isopropyl-3-{[4-(4-methylpiperazin-1-yl)phenyl]amino}pyrazine-2-carboxamide (136 mg) as a yellow solid.
