Procedure

7-(5-Fluoro-2-methylphenyl)isoquinolin-3-amine (203 mg, 806 mop and 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (313 mg, 883 mop were dissolved together in acetonitrile (2.0 mL) at ambient temperature and the mixture stirred for 16 h, at which time LCMS indicated approx 40% conversion. The mixture was diluted with water, extracted three times into dichloromethane and the combined organic phases washed with brine, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash chromatography (silica, ISCO, 0-6% methanol in dichloromethane) to yield the impure title compound as a pale solid (107 mg), used without further purification.
