Vorschrift

A solution of phenyl N′-cyano-N-[(3R,6S)-6-(2,3-difluorophenyl)-1-ethyl-2-oxoazepan-3-yl]imidocarbamate (166 mg, 0.402 mmol) and 2-oxo-1-(4-piperidinyl)-2,3-dihydro-1H-imidazo[4,5-b]pyridine dihydrochloride (116 mg, 0.402 mmol), in 1-pentanol (10 mL) was treated with N,N-diisopropylethylamine (52 mg, 0.402 mmol). This mixture was heated to reflux for 24 h. Concentration and purification by silica gel chromatography (0%→10% methanol/dichloromethane) followed by reverse phase HPLC (C-18, 95% water/acetonitrile→5% water/acetonitrile with 0.1% trifluoroacetic acid) gave the title compound (10 mg). MS 537.5 (M+1).
