Procedure

Following the method described in Example 19, 5-fluoro-3-(2-vinyl-7H-furo[3,4-b]pyridin-5-ylidene)-1,3-dihydro-indol-2-one (65 mg, 0.22 mmol) and (2-methoxyethyl)methylamine (300 mg, 3.99 mmol) and AcOH (12 drops) are heated 100° C. for 2 h. Additional (2-methoxyethyl)methylamine is added and heating is continued for 1 hr. The reaction mixture is cooled and treated with triethylamine (10 drops). The reaction mixture is loaded onto silica gel and purified by chromatography (silica gel, MeOH-Chloroform). The product containing fractions are concentrated and the residue is triturated with EtOAc-hexane. The solid which formed is collected by filtration and dried under vacuum to provide the title compound (53 mg, 65%) as a yellow solid.
