실험 절차

To the solution of 2.3 g (0.1 mol) sodium in 250 ml ethanol one adds 19.7 g 2-[2-(2-pyridinyl)-ethenyl]-phenol, stirs for 10 min at room temp., adds thereto 17.4 ml (0.11 mol) 5-bromovaleric acid ethyl ester and heats to reflux for 16 h. One evaporates, mixes with water, extracts with dichloromethane, dries the extract and evaporates. There remain 32.4 g of title compound (100% of theory) as oil.
