Versuchsvorschrift

A mixture of 10.5 mg of methyl 1H-indole-4-carboxylate, 18.2 mg of 2-(2-(3-(chloromethyl)benzamido)-5-(piperidin-1-yl)phenyl)-N-(3-(trifluoromethyl)benzyl)-isonicotinamide 8.1a, and excess potassium carbonate in 300 μL of DMF was stirred for 24 h. The solvent was evaporated and the residue was purified by silica gel chromatography. The product was dissolved in 1 mL of 4:1 THF/water and treated with 10 mg of LiOH.H2O. After stirring 4 days at 70° C. the reaction mixture was acidified with 3.0 N hydrochloric acid and then extracted with ethyl acetate. The aqueous phase was washed with ethyl acetate, and the combined organic extracts washed with brine and dried (NaSO4). The residue was purified by reverse phase HPLC eluting with 0.1% TFA in a water/acetonitrile gradient to give 10.6 mg of product. MS (ES, m/z) 732.4 [M+H]+.
