Procedure

1-(4-Nitrophenyl)piperazine and ethyl 4—bromobutanoate were allowed to undergo the reaction under heating in 1-methyl-2-pyrrolidone in the presence of potassium carbonate. The resulting compound was subjected to catalytic hydrogenation in the same manner as shown in Reference Example 3 to obtain ethyl 4-[4-(4-aminophenyl)-piperazin -1-yl]butanoate. F: 264.
