Procedure

560 mg (2.4 mMol) 5-tert-butyl-2-(4-fluoro-phenyl)-2H-pyrazol-3-ylamine and 763 mg (2.4 mMol) 6-(6-chloropyrimidin-4-yloxy)-naphthalene-1-carbonyl chloride (see Step 19.3) are dissolved in 5 ml CH2Cl2 and cooled to 0° C. 193 μl (2.4 mMol) Pyridine are added dropwise and after complete addition the reaction is allowed to warm to rt. It is stirred for 2 h at ambient temperature. The reaction is concentrated under reduced pressure and the remaining crude product is purified by flash chromatography (combi-flash, 40 g column; CH2Cl2/MeOH; gradient 0-5% MeOH) to give the title compound as a yellow foam: MS: [M+1]+=517.
