Procedure

A solution of 0.27 g (11.5 mmol) of lithium hydroxide in 3 ml of water and 15 ml of methanol is cooled to -15° C. 1.5 g (5.19 mmol) of the product obtained in Example 96 are added slowly thereto with stirring. The stirring is continued for one hour. The mixture is acidified with dilute hydrochloric acid solution. The temperature is allowed to rise to 0° C. and stirring is continued for 30 min. The mixture is filtered and the title product is collected in the form of a white powder which is washed with t-butyl methyl ether.
