Versuchsvorschrift

6-(3-Aminophenyl)-2-cyclopropyl-7-fluoro-5-methyl-1,3-benzoxazole-4-carbonitrile (I-178) (200 mg, 0.65 mmol) was dissolved in dimethyl sulfoxide (4 ml), then at room temperature, triethylamine (136 μl, 0.98 mmol) and (3S)-3-(dimethylamino)pyrrolidine (124 μl, 0.98 mmol) were added. The solution was stirred under nitrogen atmosphere at 90° C. for 19 hours, then cooled to room temperature. This was fractionated with ethyl acetate and an aqueous saturated sodium hydrogencarbonate solution.
