Procedure

A pressure-resistant vial was charged with 8-chloro-3-methoxy-1,5-naphthyridine (1200 mg, 6166 mmol), boron tribromide (6412 μl, 67825 μmol) and dichloroethane (10277 μl, 6166 μmol). The vessel was sealed and the mixture was stirred at 60° C. for 16 h. The reaction mixture was carefully diluted with DCM, and the solids were filtered.
