Versuchsvorschrift
84.2 (0.26 mol) of the ester from step 2 are suspended in 1 l of water and mixed with 30.8 g (0.77 mol) of sodium hydroxide platelets. After 2 hours cooking under reflux the starting material is cooled and the solution is adjusted to a pH value of 2.1 with 2 N hydrochloric acid. The precipitated material is filtered by suction, washed with water and dried in vacuum at 50° C. The yield amounts to about 45.6 g 95.4% of the theoretical yield).
