Reaction Steps

8-Bromo-2-ethyl-2,3-dihydroimidazo[1,2-c]pyrimidine (3.0 g) was dissolved in toluene (60 mL), then activated manganese(IV) dioxide (3.5 g) was added thereto, and the mixture was heated under stirring at 90° C. for 1 day. Manganese(IV) oxide was filtered off through Celite, and the solvent was evaporated. The resulting residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:10) to give the title compound (1.3 g) as white crystals.
