Versuchsvorschrift
A solution of 1.6 g N-(7-methyl-3-oxo-1-propyl-4-indanyl)oxamic acid ethyl ester in 100 ml methanol is heated at reflux with 5.28 ml of 1 M aqueous NaOH for 30 minutes. The solution is concentrated, diluted with water, filtered through a filtering aid such as Hyflo (Registered Trade Mark), and made acid with 2 N HCL. The title compound is filtered off and dried. M.Pt. 157°-158°.
