Procedure

A mixture of 3-amino-4-{(3S)-3-[(tert-butoxycarbonyl)amino]piperidin-1-yl}-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (15.0 mg, 0.0384 mmol), 6-[2,6-difluoro-4-(methylsulfonyl)phenyl]-5-fluoropyridine-2-carboxylic acid (15.3 mg, 0.0461 mmol), HATU (36.5 mg, 0.0960 mmol) in DMF (0.09 mL) and DIPEA (14.9 mg, 0.115 mmol) was stirred at room temperature for 16 h. The mixture was filtered, concentrated under reduced pressure and purified by preparative LC-MS (method; 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 (11.0 mg, 41%). LCMS calc. for C33H37F3N5O7S (M+H)+: m/z=704.2. Found: 704.2.
