Versuchsvorschrift

To 1-({4-(8-chloro-2-ethoxy-quinolin-4-yloxy)-1-[3,3-dimethyl-2-(1-trifluoromethyl-cyclobutoxycarbonylamino)-butyryl]-pyrrolidine-2-carbonyl}-amino)-2-ethyl-cyclopropanecarboxylic acid (110 mg, 0.15 mmol) in DMF (3 mL, 0.05 M) was added i-Pr2EtN (90 μL, 0.38 mmol) and HATU (86 mg, 0.23 mmol) and stirred 1 h at rt. To the reaction mixture at rt was added sulfamic acid cyclopropyl ester (46 mg, 0.30 mmol) and DBU (90 μL, 0.60 mmol). The reaction was stirred 17 h at rt, and then added to 5% aq citric acid and extracted with ethyl acetate. The combined organic extracts were washed water, and brine, and subsequently dried over magnesium sulfate. Concentration, followed by purification by reverse phase HPLC and lyophilization gave {1-[4-(8-chloro-2-ethoxy-quinolin-4-yloxy)-2-(1-cyclopropoxysulfonylaminocarbonyl-2-ethyl-cyclopropylcarbamoyl)-pyrrolidine-1-carbonyl]-2,2-dimethyl-propyl}-carbamic acid 1-trifluoromethyl-cyclobutyl ester (20 mg, 16% yield) as a white powder. 1H NMR (CD3OD, 500 MHz) δ 9.18 (s, 1H), 7.95 (d, 1H), 7.70 (d, 1H), 7.20 (dd, 1H), 6.48 (s, 1H), 5.4 (br s, 1H), 4.45-4.6 (m, 4H), 4.2-4.3 (m, 2H), 2.58-2.62 (m, 1H), 2.2-2.4 (m, 4H), 1.5-1.7 (m, 4H), 1.43 (t, 3H), 1.2-1.3 (m, 3H) 1.2 (dd, 2H), 1.1-0.9 (m, 13H), 0.85 (m, 2H).
