To an ice cooled mixture of 4-(4′-methylbiphenyl-2-carboxamido)-N-methyl-N-[2-[3-(4-methylpiperazin-1-yl)carbonylamino-(1-propyn-1-yl)]phenyl]benzamide (250 mg) and nickel chloride hexahydrate (297 mg) in a mixture of tetrahydrofuran (5 ml) and methanol (5 ml) was added sodium borohydride in small portions and the mixture was stirred at the same temperature for 1 hour. The mixture was filtered through bed of Celite and the filtrate was evaporated in vacuo. The residue was dissolved in chloroform (20 ml) and washed with water and brine. The organic solution was dried over magnesium sulfate and the solvent was evaporated in vacuo to give a syrup. The residue was solidified with diethyl ether to give 4-(4′-methylbiphenyl-2-carboxamido)-N-methyl-N-[2-[3-(4-methylpiperazin-1-ylcarbonyl)aminoprop-1-yl]phenyl]benzamide (75.0 mg) as a powder.
