Procedure

To a solution of 1-{[4-(7-methoxy-2-phenyl-quinolin-4-yloxy)-pyrrolidine-2-carbonyl]-amino}-2-vinyl-cyclopropanecarboxylic acid ethyl ester (600 mg, 1.115 mmol) in CH3CN (20 mL) was 2-methoxycarbonylamino-3,3-dimethyl-butyric acid (317 mg, 1.673 mmol), DIEA (0.97 mL, 5.575 mmol) and the coupling reagent HOBt (256 mg, 1.673 nunol) and HBTU (634 g, 1.673 mmol). The solution was stirred at rt. overnight. Then it was concentrated, washed with water and extracted with ethyl acetate twice. The combined organic layers were washed with brine, dried over MgSO4 and concentrated to give yellowish oil. It was then purified by Prep. HPLC column to give a yellowish oil as product.
