الإجراء التجريبي

The same product as that of paragraph (d) of Example 5 can also be obtained by treating 3-carboethoxy-2-cyano-3,5-dimethylcyclopentanone [see paragraph (a) of Example 5] with Caroat, acidifying the resulting mixture of pH 1 and then refluxing the mixture for 24 hours. Working-up as described in paragraph (d) of Example 5 yields 70% of pure crystalline 3,5-dimethylcyclopent-2-en-5-olone of melting point 92°-93° C. (from water).
