Procedure

A mixture of 1.43 g (0.013 mol) 1,4-dihydroxybenzene, 1.15 g (0.013 mol) 3-chloropropionitrile and 15 ml (2N, NaOH) in 15 ml DMF anmd 50 ml THF is stirred overnight at 60° C. bath temperature. The reaction mixture is poured into water and extracted with ether. The ether extract is washed with water, dried and concentrated to dryness under reduced pressure. The residue is passed through a silica gel column using hexane/ethylacetate (3:1) as eluent. Evaporation of eluent gives the desired product which is used directly in the next step.
