Versuchsvorschrift

Through the procedure as employed in Production step 1, an amine moiety derived from 1-methylpiperazine (1.03 g) was introduced into 5-bromo-2-furaldehyde (602 mg), to thereby yield 5-(4-methyl-piperazin-1-yl)-furan-2-carbaldehyde (yield: 447 mg, 67%). The produced 5-(4-methyl-piperazin-1-yl)-furan-2-carbaldehyde (388 mg) was condensed with 3,4-dimethoxybenzyl cyanide (355 mg) through Method A (production step 2), to thereby yield the target product (yield: 215 mg, 30%).
