In analogy to the procedures described for example 1, for intermediate 5B and for intermediate 1, the title compound has been prepared by the following reaction sequence: i) 6-chloro-2,4-dimethyl-nicotinic acid ethyl ester [Zhou, Y.; Bridger, G. J.; Skerlj, R. T.; Bogucki, D.; Yang, W.; Bourque, E.; Langille, J.; Li, T.-S.; Metz, M. U.S. Pat. Appl. Publ. (2005), US 2005277668 A1] was reacted with 3-trifluoromethoxy-phenyl boronic to give 2,4-dimethyl-6-(3-trifluoromethoxy-phenyl)-nicotinic acid ethyl ester; ii) 2,4-dimethyl-6-(3-trifluoromethoxy-phenyl)-nicotinic acid ethyl ester has been saponified to give 2,4-dimethyl-6-(3-trifluoromethoxy-phenyl)-nicotinic acid; iii) 2,4-dimethyl-6-(3-trifluoromethoxy-phenyl)-nicotinic acid was converted into its acid chloride and reacted with 4-pyrrolidin-1-yl-piperidine to give the title compound as light yellow oil. MS: 448.2 (MH+).
