To a solution of 45.0 mg (0.098 mmol) of the oxadiazole from Example 25A in 0.61 ml of ethanol were added 143 mg (1.96 mmol) of diethylamine, and then the reaction mixture was stirred in the microwave at 80 for 5 h. Another 143 mg (1.96 mmol) of diethylamine were added and the mixture was stirred in the microwave at 80° C. for a further 2 h. The solvent was removed under reduced pressure and the crude product was purified by means of preparative HPLC. Yield: 35.6 mg (80% of theory)
