Versuchsvorschrift

To a solution of 110 mg (0.25 mmol) of the crude 7-[2-(3-chloro-pyridin-2-yl)-5-trifluoromethyl-2H-pyrazol-3-yl]-1H-8-oxa-1,6-diaza-cyclopenta[a]naphthalen-9-one in 2.5 mL of anhydrous tetrahydrofuran, under Argon, is added 0.07 mL (0.77 mmol) of isopropylamine. The reaction is stirred during 5 hours at ambient temperature and then quenched with an aqueous saturated solution of ammonium chloride. The product is extracted twice with ethyl acetate and the combined organic phases are dried on Na2SO4, filtrated and the solvent is evaporated. After purification by flash chromatography on silica gel with hexanes and ethyl acetate as eluents and a preparative thin layer chromatography, 18.5 mg (0.04 mmol, 16%) of a white solid are obtained; LC/MS:513/515 (M+Na)+, m.p.: 240-242° C.
