Procedure

A solution of 7-[2-(3-chloro-pyridin-2-yl)-5-methoxy-2H-pyrazol-3-yl]-2-(4-methoxy-benzyl)-5-methyl-2H-8-oxa-1,2,6-triaza-cyclopenta[a]naphthalen-9-one (0.100 g, 0.189 mmol) in tetrahydrofurane (2 ml) was treated with 16 drops of isopropyl amine and stirred at 20° C. for three hours. The reaction mixture was evaporated and the crude product was purified by flash chromatography on silica gel using a mixture of 75% ethyl acetate 25% cyclohexane. The desired product showed the physical data reported in the corresponding table (P.34.).
