Versuchsvorschrift

An N,N-dimethylformamide dimethylacetal (2 ml) solution containing 1-(5-bromopyridin-3-yl)ethanone (100 mg) (WO2009/87224 A1) was stirred at 100° C. for 5 hours. The solvent was distilled away under reduced pressure, and a yellow solid of 1-(5-bromopyridin-3-yl)-3-(dimethylamino)prop-2-ene-1-one was thus obtained.

Aufarbeitung
