Versuchsvorschrift

48 μl (0.68 mMol) acetyl chloride are added portionwise to a solution of 300 mg (0.68 mMol) 6-(2-amino-pyrimidin-4-yloxy)-naphthalene-1-carboxylic acid (4-fluoro-3-trifluoromethyl-phenyl)-amide (step 10.3) in 3.7 ml CH2Cl2 and 5.5 ml pyridine. After 1.5 h, the solution is diluted with EtOAc and water, the aq. phase separated off and extracted twice with EtOAc. The organic layers are washed with water and brine, dried (Na2SO4) and concentrated. Chromatography (Combi Flash; hexane/EtOAc 1:1→1:3) gives the title compound: m.p.: 213-214° C.
