Procedure

4.98 g 3-methyl-4-methylsulfonylamino-1-propyl-imidazo[1,5-a]pyrido[3,2-e]pyrazin-8-ol (Example 86) and 1.6 g sodium hydroxide were dissolved in 20 ml dimethylformamide. After 10 min stirring 1.85 ml chlorodifluoroacetic acid was added dropwise. The mixture was heated 5 h at 150° C. bath temperature with stirring. After cooling the product was extracted with ethyl acetate (200 ml, 300 ml), the combined organic phases were washed with water (2×100 ml), the organic phase was dried over sodium sulfate, filtered off, and evaporated to dryness.
