Procedure
18.6 g (87.3 mmol) of 2-acetoxy-8-vinylquinoline, 290 ml of water and 290 ml of methanol are placed in a 1 l round-bottomed flask. The reaction mixture is heated at 55° C. for 2 h and then the methanol is evaporated under vacuum. Extraction is carried out with ethyl acetate (2×200 ml). The organic phases are combined, dried over magnesium sulfate, filtered and concentrated under vacuum to provide 15.0 g of 2-hydroxy-8-vinylquinoline in the form of a yellow solid; M.p.=96° C. (Quantitative yield)
