3-[1-(2-Aryl-2-hydroxyethyl)-4-piperidylidene]-1,3-dihydro-2H-indol-2-one with structure II, as potential antihypertensive agent was synthesized. The intermediates, 3-[1-(2-aryl-2-oxoethyl)-4-piperidylidene]-1,3-dihydro-2H-indol-2-one (5) were prepared from 4-piperidone via 4 steps. Selective reduction of carbonyl group in 5 was realized using diisobutyl aluminium hydride to afford compound II.
