実験手順

A mixture of 3-amino-4-{(3S,5R)-3-[(tert-butoxycarbonyl)amino]-5-methylpiperidin-1-yl}-6,7-dihydro-5H-cyclopenta[b]pyridin-7-yl acetate (10.0 mg, 0.025 mmol), 6-[2,6-difluoro-4-(methylsulfinyl)phenyl]-5-fluoropyridine-2-carboxylic acid (9.4 mg, 0.03 mmol), HATU (23.5 mg, 0.062 mmol) in DMF (0.06 mL) and DIPEA (9.6 mg, 0.074 mmol) was stirred at room temperature for 16 h. The mixture was filtered, concentrated 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, 17%). LCMS calc. for C34H39F3N5O6S (M+H)+: m/z=702.3. Found: 702.2.
