Versuchsvorschrift

(2-(tert-Butoxy)-4-(4-(trifluoromethoxy)benzyl)quinolin-6-yl)(4-chlorophenyl)(thiazol-2-yl)methanol (55 mg, 0.0918 mmol) and tin(II) chloride dihydrate (83 mg, 0.367 mmol) were combined in AcOH (2 mL). HCl (conc. 36%, 0.115 mL) was then added. The solution was heated to 110° C. After 45 min the reaction was cooled to room temperature and concentrated. The residue was taken up in CH2Cl2 and washed with NaHCO3 (satd), dried (Na2SO4) and concentrated. The resulting residue was purified by silica column (70-80% EtOAc/hexanes) chromatography to yield 6-((4-chlorophenyl)(thiazol-2-yl)methyl)-4-(4-(trifluoromethoxy)benzyl)quinolin-2(1H)-one.
