Procedure

55 mg (0.43 mmol) of 2-amino-4-fluoropyridin-3-ol Example 109A, 98 mg (0.47 mmol) of 2-(bromomethyl)-1,3-difluorobenzene and 308 mg (0.95 mmol) of caesium carbonate were initially charged in 1 ml of dry DMF and heated in an oil bath warmed to 50° C. for 15 min. The mixture was then filtered off and purified by preparative HPLC (Method 9). This gave 70 mg of the title compound (64% of theory).
