Procedure

A stirred yellow suspension of 5-(2-diethylamino-ethyl)-2-(5-fluoro-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-3-methyl-1,5,6,7-tetrahydro-pyrrolo[3,2-c]pyridin-4-one (200 mg, 0.49 mmol) obtained form Example 1 in methanol (4 ml) and dichloromethane (8 ml) was added with methane sulfonic acid (32 μl, 0.49 mmol) at room temperature. The resulting solution was stirred for 30 minutes. The solvent was evaporated under reduced pressure and the residue was added with 5 ml of acetonitrile. The resulting solution was heated to reflux for 30 minutes, cooled down to room temperature and filtered. The filter cake was washed with cold acetonitrile (0.5 ml×3) and ethanol (0.5 ml×3) and dried in vacuo to give the title compound 6-(2-diethylamino-ethyl)-2-(5-fluoro-2-oxo-1,2-dihydro-indol-3-ylidenemethyl)-3-methyl-1,5,6,7-tetrahydro-pyrrolo[3,2-c]pyridin-4-one mesylate (174 mg, 73.1%) as a yellow solid.
