0.8 g (5.51 mmol) of quinoline N-oxide is dissolved in 15 ml of anhydrous THF at 20° C., in a dry round-bottomed flask equipped with a magnetic stirrer and a nitrogen inlet. This solution is treated with 0.78 ml (6.07 mmol) of isobutyl chloroformate; the suspension obtained is cooled to −78° C. 11 ml (11 mmol) of a 1M solution of vinylmagnesium bromide in THF are then added dropwise. After stirring for 90 minutes at −78° C., the solution is slowly returned to ambient temperature (30 minutes), and then hydrolyzed with 15 ml of water.
