Procedure

1-(4-Nitrophenyl)piperazine and 4-bromobutyronitrile were allowed to undergo the reaction under heating in 1-methyl-2-pyrrolidone in the presence of potassium carbonate. The resulting compound was allowed to react with polyphosphoric acid under heating and then subjected to catalytic hydrogenation in the same manner as shown in Reference Example 3 to obtain 4-[4-(4-aminophenyl)piperazin-1-yl]butanamide. F: 263.
