1-Methylpiperazine → HCID 67226785, compound

Participants

Reaction Steps

Through the procedure as employed in Production step 1, an amine moiety derived from 1-methylpiperazine (6.01 g) was introduced into 5-bromothiophene-2-carboxaldehyde (3.82 g), to thereby yield 5-(4-methyl-piperazin-1-yl)-thiophene-2-carbaldehyde (yield: 3.71 g, 88%). The produced 5-(4-methyl-piperazin-1-yl)-thiophene-2-carbaldehyde (2.10 g) was condensed with 3,4-dimethoxybenzyl cyanide (1.77 g) through Method A (production step 2), to thereby yield the target product (yield: 2.47 g, 67%).
