Versuchsvorschrift

A solution of 7-bromo-1-chloroisoquinoline (750 mg, 3.09 mmol) in N-methylbutylamine (7.0 mL) was heated at 65° C. in a sealed tube for 18 h. The reaction mixture was concentrated under reduced pressure. The residue was diluted with chloroform and washed with saturated sodium bicarbonate, dried (sodium sulfate), filtered, and concentrated under reduced pressure to yield a brown oil. Purification by flash column chromatography (silica, 3:1 hexanes/diethyl ether) provided 7-bromo-N-butyl-N-methylisoquinolin-1-amine (730 mg): ESI MS m/z 293 [M+H]+.
