Versuchsvorschrift

Mix 5-amino-2-bromobenzonitrile (0.76 mmol) in anhydrous THF (3 ml), N,N-diisopropylethylamine (0.92 mmol), and bromoacetonitrile (1.0 mmol) at room temperature under inert atmosphere. Heat the mixture to 100° C. for 16 h in a sealed tube. Cool in ice bath, filter the precipitate and evaporate the filtrate to dryness to afford a crude residue. Purify by flash chromatography (Silica gel-CHCl3/Ethanol/NH4OH 9:1:0.1) to yield the title compound.
