Versuchsvorschrift
A solution of methanesulphonic acid (0.1 mmol; 1 ml; 0.1N in acetone) is added to a solution of the compound of Example 5 (0.1 mmol; 34 mg) in acetone (2 ml). The precipitate is filtered, washed with acetone and dried under reduced pressure. 24 mg of the expected product is obtained in the form of a white powder. Melting point: 220° C.
