Reaction Steps

1-(4-nitrophenyl)piperazine and N,N-dimethylglycine hydrochloride were allowed to undergo the reaction using WSC hydrochloride and HOBt in 1-methyl-2-pyrrolidone in the presence of triethylamine. The resulting compound was subjected to-catalytic hydrogenation in the same manner as shown in Reference Example 3 to obtain 1-[4-(4-aminophenyl)piperazin-1-yl]-2-dimethylaminoethanone. NMR2: 2.30 (6H, s), 3.74-3.76 (4H, m), 6.64-6.68 (2H, m).
