Versuchsvorschrift

A mixture of 3-amino-4-{(3S)-3-[(tert-butoxycarbonyl)amino]piperidin-1-yl}-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (12.0 mg, 0.031 mmol), 6-[2,6-difluoro-4-(methylsulfinyl)phenyl]-5-fluoropyridine-2-carboxylic acid (11.6 mg, 0.037 mmol), HATU (29.2 mg, 0.077 mmol) in DMF (0.07 mL) and DIPEA (11.9 mg, 0.092 mmol) was stirred at room temperature for 16 h. The reaction mixture was filtered, concentrated under reduced pressure and purified by preparative LC-MS (XBridge™ preparative C18 5 μm OBD™ column, 30×10 mm, 60 mL/min., eluting with a gradient of MeCN and water with 0.1% NH4OH) to give the sub-title compound as a colorless gum (3.0 mg, 14%). LCMS calc. for C33H37F3N5O6S (M+H)+: m/z=688.2. Found: 688.2.
