Procedure

169.5 g of the compound from Example 13A in 970 ml of 30% strength aqueous potassium hydroxide solution were heated under reflux for 20 hours. After cooling, the reaction mixture was adjusted to pH 2 by addition of 670 ml of concentrated aqueous hydrogen chloride solution, the precipitate was filtered off with suction and the filtrate was concentrated. This gave 110.7 g of a crude product as a mixture of diastereomers which still contains salts and was reacted without further purification.
