Reaction Steps

1.50 g (4.77 mmol) of 2-(4-ethoxy-2,3-difluorophenyl)-5-propenyltellurophene are hydrogenated in 15 ml of THF, in the presence of Pd/C (5% of Pd) at atmospheric pressure and RT. The reaction soln. is filtered and concentrated to dryness, and the crude product is purified by column chromatography (SiO2, n-heptane:toluene=3:1). The further purification is carried out by recrystallisation from n-heptane. 2-(4-Ethoxy-2,3-difluorophenyl)-5-propyltellurophene is obtained as a colourless solid (m.p. 76° C.).
