In analogy to the procedure described in example 9.6, [2-(4-chloro-phenyl)-2,4,5,6,7,8-hexahydro-cycloheptapyrazol-3-yl]-cyclohexyl-acetic acid (example 9.3) was converted into the corresponding acid chloride with thionyl chloride which subsequently reacted with 4-amino-3-fluoro-benzoic acid methyl ester (CAS Reg. No. 185629-32-7) in the presence of DMAP to give the title compound as off-white solid. MS: m/e=538.3 [M+H+].
