Procedure

TFA (5 mL) was added at room temperature to a solution of 2-(1-ethoxycarbonyl-2-vinyl-cyclopropylcarbamoyl)-4-[2-(6-isopropyl-pyridin-2-yl)-7-methoxy-8-methyl-quinolin-4-yloxy]-cyclopentanecarboxylic acid tert-butyl ester (109, 590 mg, 0.90 mmol) and triethylsilane (280 mg, 2.5 eq) in CH2Cl2 (5 mL). After 2 h, the reaction mixture was concentrated under reduced pressure to afford the desired product 110, which was used in the next step without further purifications.
