Reaktionsschritte
A solution of 3-chloro-4-fluoro-benzonitrile (236 mg, 1.52 mmoles), piperazine (784 mg, 9.1 mmoles) and potassium carbonate (276 mg, 2 mmoles) in acetonitrile (5 mL) was heated to 100° C. overnight. The mixture was cooled, filtered and the filtrate concentrated under reduced pressure. The crude residue was purified by column chromatography (silica gel, 0-5% 2N methanolic ammonia in DCM) to provide the title compound. MS(APCI+) m/z 222 (M+H)+.
