実験手順

Through the procedure as employed in Production step 1, an amine moiety derived from N,N,N′-trimethylethylenediamine (3.06 g) was introduced into 5-bromo-2-furaldehyde (1.75 g), to thereby yield 5-(4-methyl-piperazin-1-yl)-furan-2-carbaldehyde (yield: 1.18 g, 60%). The produced 5-(4-methyl-piperazin-1-yl)-furan-2-carbaldehyde (1.18 g) was condensed with 3,4-dimethoxybenzyl cyanide (1.06 g) through Method A (production step 2), to thereby yield the target product (yield: 2.06 g, 96%).
