Procedure
Trans-{4-[(Quinoline-4-carbonyl)-amino]-cyclohexyl}-thioacetic acid S— ethyl ester (1.87 g, 5 mmol) was solved in acetone/methylene chloride (40/40 mL), 0.8 g of molecular sieves were added to the mixture and the solution was stirred for 0.5 h. Then 0.558 g (1 mmol) of palladium on active charcoal 10% was added followed by 1.25 mL (8 mmol) of triethyl-silane. The reaction was stirred for 1.5 hours at room temperature and additional 0.558 g (1 mmol) of palladium on active charcoal 10% and 1.25 mL (8 mmol) of triethyl-silane were added and the stirring was continued for another hour. The mixture was filtrated through celite and the mother liquid was concentrated to obtain after chromatography using heptane/acetate 1:1 1.1 (37.1 mmol, 70.8% yield) of the final compound. MS (m/e): 297.3 (M+H+)
