Versuchsvorschrift

A solution of 180 mg (0.31 mmol) of methyl 4-[(3-methyl-2-{4-[(5-oxo-2-phenyl-5,6-dihydro-4H-1,3,4-oxadiazin-4-yl)methyl]phenyl}pentanoyl)amino]-2,3-dihydro-1H-indene-2-carboxylate (Example 147A) in 3.6 ml of THF and 1.3 ml (1.3 mmol) of 1 N aqueous sodium hydroxide solution was stirred at room temperature overnight. After the reaction had gone to completion, the THF was removed under reduced pressure and the reaction solution was diluted with water and then adjusted to pH 2 with 1 M hydrochloric acid. The precipitated solid was filtered off, washed with water and dried under reduced pressure at 45° C. overnight. This gave 159 mg (0.29 mmol, 91% of theory) of the title compound as a mixture of isomers.
