Procedure
A mixture of 5-fluoro-6-(1-(4-fluorobenzyl)-5 methanesulfonyl-1H-pyrrolo[2,3-b]pyridin-2-yl)-3H-pyrimidin-4-one obtained in Example 36 (4) (20 mg) and phosphorus oxychloride (1 ml) was heated, under reflux for 3 hours. The mixture was concentrated under reduced pressure, diluted with dichloromethane, washed with water, dried and concentrated under reduced pressure. The resulting residue was separated using silica gel column chromatography (methanol:dichloromethane=1:99) to obtain the desired product (13 mg) as a white powder.
