3-{[4-(2,6-Dichlorophenyl)piperidin-1-yl]methyl}-2-(thiophen-2-yl)-1H-indole (1) as a ligand for opioid receptor like 1 receptor was prepared via four steps from commercially available phenylhydrazine (2), 1-(thiophen-2-yl)- ethanone (3), 2,6-dichloro- phenyl-boronic acid (5) and 4-bromopyridine (6). This convenient approach was green and had potential application for the scale production because of recoverable reaction medium, simple isolating process of intermedi-ates, little waste and highly total yield of 65%.
