Procedure

A solution of 2-(1-ethoxycarbonyl-2-vinylcyclopropylcarbamoyl)-4-hydroxycyclo-pentanecarboxylic acid tert-butyl ester (500 mg, 1.5 mmol), prepared as described in WO2005/073195, 4-hydroxy-2-(6-methyl-2-pyridyl)-7-methoxy-8-methylquinoline (97, 504 mg, 1.8 mmol) and triphenylphosphine (990 mg, 3.75 mmol) were stirred in dry THF (40 mL) at 0° C. for 10 min. Then, DIAD (0.74 mL, 3.75 mmol) was added drop wise. The resulting reaction mixture was stirred at a temperature from 0° C. to 22° C. overnight. Then, volatiles were evaporated and the residue was purified by column chromatography on silica gel (gradient CH2Cl2/AcOEt, 1:0 to 95:5) to give 1.1 g (88%) of the title compound 98: m/z=630 (M+H)+.
