Reaction Steps

To a solution of 7-fluoro-6-methoxyisoquinolin-1(2H)-one (6.3 g, 32.6 mmol) in methanol (70 ml) was added iodozobenzenediacetate (10.5 g, 32.6 mmol) followed by methane sulphonic acid (3.76 g, 39.1 mmol) at room temperature. The reaction mass was heated at reflux for 3 h. The solvent was evaporated and the residue was diluted with cold water. The precipitated solid was filtered, washed with water to get crude compound (6.6 g, 91%) as a light red colored solid. MS: MS m/z 224.0 (M++1).
