1-(2-Hydroxyethyl)piperazine → HCID 11965334, compound

Participants

Reaction Steps

Through the procedure as employed in Production step 1, an amine moiety derived from 1-piperazineethanol (7.81 g) was introduced into 5-bromothiophene-2-carboxaldehyde (3.82 g), to thereby yield 5-[4-(2-hydroxy-ethyl)-piperazin-1-yl]-thiophene-2-carbaldehyde (yield: 3.22 g, 67%). The produced 5-[4-(2-hydroxy-ethyl)-piperazin-1-yl]-thiophene-2-carbaldehyde (1.85 g) was condensed with 3,4-dimethoxybenzyl cyanide (1.37 g) through Method A (production step 2), to thereby yield the target product (yield: 1.51 g, 49%).
