Reaction Steps

To 10.0 g of 3-(3-fluorophenyl)-1H-5-indazolecarbonitrile were sequentially added 50 ml of glacial acetic acid, 15 ml of water and 12 ml of concentrated sulfuric acid, and the mixture was stirred at 110° C. for 6.5 hours. After standing to cool, the reaction mixture was added with 150 ml of ice-water, and the resulting crystals were collected by filtration. The resulting crystals were dried in vacuo, to give 10.7 g of the title compound as beige orange-pink crystals.
