Popis: Reaction of 2-chlorobenzonitriles with β-ketoesters in an S N Ar reaction, followed by cyclization in acid provides a versatile route to isoquinolones. Starting from 2,6-dichloro-3-nitrobenzonitrile 7 , sequential displacement of the chlorines by an amine and a β-ketoester leads to imidazo[4,5- h ]isoquinolin-9-ones 1 , a new class of kinase inhibitor.
