実験手順
Acetic anhydride in an amount of 10 ml is added to 1.0 g. of 1-methylazulene under cooling with ice-water, sulfuric acid in an amount of 3.4 g. is added dropwise and the reaction mixture is stirred for 4 hours at 0° C. Then, the reaction mixture is alkalized to pH8-9 by adding 40% of sodium hydroxide solution and the generated solid is collected and dried. The product is recrystalized from 95% ethanol to give 1.1 g. of the objective compound.
