Versuchsvorschrift

4-Bromo-benzonitrile (5 g) was suspended in absolute EtOH (100 ml) and cooled to 0-5° C. HCl gas was bubbled through, initially vigorously for several minutes and later slowly for 5 hours. The resulting solution was allowed to stir overnight. Most of solvent was removed and the precipitate was filtered, washed with EtOH twice and dried to afford compound 2BO (4.1 g) as white solid.
