Reaction Steps
In analogy to the procedure described in example 6, [2-(4-chloro-phenyl)-2H-indazol-3-yl]-cyclohexyl-acetic acid was converted into the corresponding acid chloride with thionyl chloride which subsequently reacted with 4-amino-3-fluoro-benzoic acid ethyl ester (CAS Reg. No. 73792-12-8) in the presence of DMAP to give the title compound as colorless oil. MS: m/e=534.3 [M+H+].
