Procedure

To a stirred solution of tert-butyl (4-(4-chloro-2-fluorophenyl)-3-formylpyridin-2-yl)carbamate (700 mg, 1.996 mmol) in ethanol (10 mL) at 0° C. was added methylamine (8M in EtOH) (620 mg, 2.49 mL, 19.96 mmol) and the reaction was stirred at rt for 5 h. After the consumption of starting material, solvent was removed under reduced pressure. The residue was washed with hexane (50 mL) and the solid so obtained was dried under vacuum to yield the fluoride salt of 4-((tert-butoxycarbonyl)amino)-8-chloro-6-methylbenzo[c][2,7]naphthyridin-6-ium fluoride (900 mg, 1.69 mmol, 84% yield) as a yellow solid. LC/MS (ESI) m/e 344.2 [(M)+, calcd for C18H19ClN3O2 344.1]; LC/MS retention time (method C): tR=1.90 min.
