実験手順
On the other hand, 15 ml of carbon tetrachloride (solvent) and 3 ml of thionyl chloride were added to 2.16 g (0.0158 mol) of 4-n-butoxycarbonyloxy benzoic acid, and the mixture was heated and refluxed. After sufficiently reacting them, excess thionyl chloride and carbon tetrachloride (solvent) were distilled off under reduced pressure to obtain 4-butoxycarbonyloxy benzoic acid chloride (one having Formula 7 wherein R2 is a n-butyl group).
