A novel, short synthetic route has been successfully developed for a key precursor of Quinazolinap ligands. The key step is a Friedel-Crafts-type reaction between 2-naphthol and 4-chloroquinazoline, with moderate to quantitative yields recorded. A variation of this reaction allows for the introduction of an amine group on the naphthalene unit.
