Procedure
The compound of step 1 was coupled to 3-trifluoromethyl-phenylboronic acid in analogy to step 3 of example 92, the obtained ester intermediate was hydrolyzed in analogy to step 4 of example 1 to yield 6-(2-Hydroxy-ethoxy)-3′-trifluoromethyl-biphenyl-3-carboxylic acid. This intermediate was coupled to trans-1-amino-4-ethylcyclohexanecarboxylic acid methylester hydrochloride in analogy to step 1 of example 3, and the obtained ester intermediate was hydrolyzed in analogy to step 4 of example 1 to yield the title compound.
