实验步骤: The title compound was prepared in analogy to Example 1, from 2,5-dichloro-4-[3-(4-cyclopropyl-3,4-dihydro-2H-quinoxaline-1-carbonyl)-pyridin-4-yloxy]-benzoic acid (Example 29, intermediate) and 4-amino-heptanedioic acid dimethyl ester (J. Am. Chem. Soc. 2005, 127 (50), 17877-17887) and using a gradient of n-heptane:ethyl acetate (100:0 to 0:100) for the chromatographic purification. Light brown foam (69%). MS (ESI): m/z=669.19 [M+H]+. for the chromatographic purification
