Versuchsvorschrift
100 mg (0.213 mmol) of 2-methyl-2-[4-(3-methyl-2-oxo-8-quinolin-3-yl-2,3-dihydro-imidazo[4,5-c]quinolin-1-yl)-phenyl]-propionitrile (Example 7) and 95 mg (0.234 mmol) Lawesson reagent (Fluka, Buchs, Switzerland) in 1 ml of dioxane are heated at 100° C. for 96 h. The reaction mixture is quenched with sat. aqueous NaHCO3 and extracted with CH2Cl2 (2×). The organic layers are washed with sat. aqueous NaHCO3, dried over Na2SO4, filtered and evaporated. The residue is purified by preparative HPLC to provide the title compound as an off-white solid. ES-MS: 486 (M+H)+; analytical HPLC: tret=3.29 minutes (Grad 1).
