실험 절차

A solution of 5 g (20.1 mmol) of the allyl ether from Example 19 in 20 ml of toluene is heated at 200° C. in a sealed tube for 24 hours. After cooling to room temperature a precipitate begins forming and the reaction mixture is cooled further to 0° C. The precipitate is filtered off and allowed to air dry, giving methyl 3-allyl-4-acetylaminosalicylate which can be used directly in the next step.
