Reaction Steps

To a suspension of 210 mg (0.40 mmol) of the above 5-chloro-7-[5-chloro-2-(3-chloro-pyridin-2-yl)-2H-pyrazol-3-yl]-1H-8-oxa-1,2,6-triaza-cyclopenta[a]naphthalen-9-one in 4.2 mL of tetrahydrofuran is added 110 μl (1.3 mmol) of isopropylamine. The reaction mixture is stirred for 4 hours at ambient temperature and then concentrated in vacuo. The residue is Purification of the residue by reverse-phase chromatography affords 111 mg (52%) of the product as a white solid; LC/MS:514/516 (M+Na)+.
