Procedure

To a chilled solution of (4-hydroxy-2,2-dimethyl-3,4-dihydro-2H-quinolin-1-yl)-(3-methoxy-phenyl)-methanone (500 mg, 1.6 mmol) in 10 ml dichloromethane was added slowly 0.8 ml iodotrimethylsilane (5.6 mmol) at 0° C. The resulting reaction mixture was stirred at 0° C. for 6 hours. Then the mixture was concentrated under vacuum. The residue was dissolved in 12 ml TIF. BaCO3 (630 mg, 3.2 mmol) and aniline (0.17 ml, 1.92 mmol) was added. The mixture was stirred at RT overnight. The mixture was filtered and the filtrate was concentrated under vacuum. The residue was purified by silica gel chromatography, eluting with ethyl acetate-hexane (1:4) to give (2,2-dimethyl-4-phenylamino-3,4-dihydro-2H-quinolin-1-yl)-(3-methoxy-phenyl)-methanone (150 mg, 24%).
