Abstract A convenient and efficient synthetic route to 1-chloro-6-methoxy-isoquinolin-3-ol and its derivatives is reported. This new method involves carboxylation of 4-methoxy-2-methylbenzonitrile, subsequent conversion of the resulting 2-cyano-5-methoxy-phenylacetic acid to its acid chloride, and acid-promoted cyclization of the 2-cyano-5-methoxy-phenyl-acetyl chloride. This procedure offers a better overall yield than the previously reported route and is also less hazardous and more reproducible.
