Reaction Steps
560 mg of ethyl 6-fluoro-8-hydroxy-2-methylimidazo[1,2-a]pyridine-3-carboxylate (Example 12A; 2.4 mmol, 1.0 equivalent), 1.7 g of caesium carbonate (5.17 mmol, 2.2 equivalents) and 535 mg of 2,6-difluorobenzyl bromide (2.6 mmol, 1.1 equivalents) were initially charged in 34 ml of dry DMF, and the mixture was heated at 50° C. for 15 min. Water was added and the mixture was stirred for 30 min. The solid was filtered off and washed with water. This gave 560 mg of the title compound (65% of theory).
