To a solution of 100 mg (299 μmol) 4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazoline-2-thione in 2 ml THF are added 35.5 μl (299 μmol) benzyl bromide and 76 μl (448 μmol) DIEA. After stirring for 18 h at r.t. the reaction mixture is extracted with dichloromethane and water. After evaporation of the organic layers the crude product is purified by flash chromatography using hexanes/ethyl acetate 20:1 as eluent.
