Procedure

A mixture of 3-(2-amino-3-propyl-3,4-dihydro-quinazolin-6-yloxy)-benzoic acid (0.0009 mol) in SOCl2 (2 mL) and DCM (10 mL) was stirred for 2 hours at room temperature and then the solvent was evaporated. The obtained residue was stirred in toluene and the solvent was evaporated again to yield the title compound as a residue.
