PROCEDURE

实验过程

To a solution of 530 mg of the above 7-[2-(3-chloro-pyridin-2-yl)-5-trifluoromethyl-2H-pyrazol-3-yl]-5-ethynyl-1H-8-oxa-1,2,6-triaza-cyclopenta[a]naphthalen-9-one in 10 mL of N,N-dimethylformamide, is added 465 mg (3.48 mmol) of bicyclopropyl-1-ylamine hydrochloride and 485 μL (3.48 mmol) of triethylamine. The reaction is stirred at 50° C. for 16 hours and then concentrated in vacuo. Purification of the residue by flash chromatography (SiO2, hexane/ethyl acetate 3:7) affords 200 mg (31% over two steps) of the product as white solid; LC/MS:554/556 (M+H)+, m.p.: 246-248° C.
