Versuchsvorschrift

6-Fluoro-3,4-dihydro-2H-isoquinolin-1-one (1.56 g, 9.45 mmol) was deposited in a sealed vessel with 25 mL 33% dimethylamine in ethanol. This was heated at 150° C. for 7 hours. The resulting solution was partitioned between ethyl acetate and water. The ethyl acetate layer was washed with brine, dried over anhydrous magnesium sulfate, concentrated in vacuo, and purified by flash chromatography (elution with ethyl acetate) to yield 6-Dimethylamino-3,4-dihydro-2H-isoquinolin-1-one (787 mg, 4.14 mmol). MS (ESI) 191.1 (M+H)+.
