실험 절차

To a solution of 500 mg of the above 7-[2-(3-chloro-pyridin-2-yl)-5-methoxy-2H-pyrazol-3-yl]-5-methyl-1H-8-oxa-1,2,6-triaza-cyclopenta[a]naphthalen-9-one in 8 mL of N,N-dimethylformamide is added 244 mg (1.83 mmol) of bicyclopropyl-1-ylamine hydrochloride and 340 μL (2.44 mmol) of triethylamine. The reaction is stirred at 70° C. for 16 hours and then concentrated in vacuo. The residue is taken-up with water and ethyl acetate. The phases are separated and the aqueous layer is washed with ethyl acetate. The combined organic layers are washed several times with brine, dried over MgSO4 and concentrated in vacuo. Purification of the residue by flash chromatography (SiO2, hexanes/ethyl acetate 3:7) affords 90 mg (15% over two steps) of product as a pale yellowish solid; LC/MS:506/508 (M+H)+, m.p.: 150-154° C.
