実験手順

To a suspension of 600 mg of the above 7-[2-(3-chloro-pyridin-2-yl)-5-difluoromethyl-2H-pyrazol-3-yl]-5-methyl-1H-8-oxa-1,2,6-triaza-cyclopenta[a]naphthalen-9-one in 10 mL of acetonitrile/water (4:1, v/v), is added 1.2 mL (14.0 mmol) of isopropylamine. The reaction mixture is stirred for 6 hours at ambient temperature and then concentrated in vacuo. The residue is taken-up with brine and ethyl acetate. The phases are separated and the aqueous layer is washed with ethyl acetate. The combined organic layers are washed with brine, dried over MgSO4 and concentrated in vacuo. Trituration of the residue in ethyl acetate affords 106 mg (15% over two steps) of the product as a pale yellowish solid; LC/MS:488/490 (M+H)+; m.p.: 250-253° C.
