実験手順

The title compound was prepared in analogy to example 1, from (6-chloro-4-phenyl-pyridazin-3-yl)-methyl-amine and 3-methanesulfonyl-5-trifluoromethyl-benzoic acid (example 1, intermediate d) after a reaction time of 18 hours and using a gradient of n-heptane:ethyl acetate (100:0 to 30:70) for the chromatographic purification. Another purification step using preparative HPLC (Gemini NX column) with a gradient of methanol:water with 0.05% formic acid (80:20 to 98:2) gave the desired compound as a colorless solid (20%). MS (ESI+): m/z=470.054 ([M+H]+).
