Procedure

After adding tetrahydrofuran (2 ml) and methanol (2 ml) to 4-(2-dimethylaminoethyl)piperazine-1-carboxylic acid [6-(2-fluoro-4-nitrophenoxy)pyrimidin-4-yl]amide (94 mg) under a nitrogen atmosphere, 10% palladium-carbon (46 mg) was added, the atmosphere in the reaction vessel was replaced with hydrogen, and the mixture was stirred for 9 hours. The atmosphere in the reaction vessel was then replaced with nitrogen, and the catalyst was filtered and washed with methanol. The filtrate was concentrated under reduced pressure to provide a crude product of 4-(2-dimethylaminoethyl)piperazine-1-carboxylic acid [6-(4-amino-2-fluorophenoxy)pyrimidin-4-yl]amide (91 mg) as a pale yellow amorphous substance.
