実験手順
378 mg (2.17 mMol) methansulfonic acid anhydride are added in 3 portions 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 4.5 ml CH2Cl2 and 7.5 ml pyridine. After 20 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; CH2Cl2/THF 50:1-9:1) gives the title compound: m.p.: 246° C.; MS: [M−1]=519.
