Reaction Steps

One heats a mixture of 30 g (0.15 mol) 4-[2-(4-pyridinyl)-ethenyl]-phenol, 21 g potassium carbonate, 750 ml butanone and 33 ml (0.23 mol) 4-bromobutyric acid ethyl ester to reflux for 24 h, filters, evaporates the filtrate, mixes with water, extracts with dichloromethane, dries the extract, evaporates the triturates the residue with ether. There remain 42.3 g of title compound (89% of theory) of the m.p. 83°-85° C.
