A mixture of 5-(3-{4-amino-6-[methyl(phenyl)amino]-1,3,5-triazin-2-yl}-1,2,4-oxadiazol-5-yl)pyridin-2-ol (Intermediate 136, 0.150 g, 0.414 mmol), 2-iodoacetonitrile (0.036 mL, 0.497 mmol), cesium carbonate (0.270 g, 0.827 mmol) in DMF (2 mL) was stirred at 90 C in a pressure tube for 18 h. A further 0.6 equivalent of 2-iodoacetonitrile was added and the mixture was stirred overnight at 90 C. The reaction mixture was cooled to room temperature, diluted with water, the precipitate was collected by filtration, washed with water and dried under vacuum. The resulting solid was purified by preparative HPLC to afford the title compound (3 mg, 2%).
