Reaction Steps

The title compound was prepared in analogy to example 4 (6-(3-chloro-phenyl)-5-(2,2,2-trifluoro-ethoxy)-3-trifluoromethyl-pyrazine-2-carboxylic acid ((1R,2R)-2-hydroxy-cyclohexyl)-amide) by substituting 5-bromo-3-(3-chloro-phenyl)-6-trifluoromethyl-pyrazin-2-ylamine by N-[4-(3-amino-6-bromo-5-trifluoromethyl-pyrazin-2-yl)-phenyl]-methanesulfonamide.
