Procedure

To a solution of (6-bromo-naphthalen-2-yl)-(6,7-dimethoxy-quinolin-4-yl)-methanol (Step e, 0.55 g, 1.3 mmol) in formic acid (10 mL), was added Zn dust (500 mg, 7.6 mmol). The suspension was heated at reflux for 6 h and the solvent was removed in vacuo. The resulting residue was worked up with 1N NaOH and extracted with CH2Cl2 3×. The combined organic layer was washed with water and brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude was purified with silica gel column chromatography (40-65% EtOAc/Hexane) to give the titled compound. MS (ESI, pos. ion) m/z: 408.1 (M+1).
