Procedure

126 μl (1.64 mMol) methyl chloroformate 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 7 ml CH2Cl2 and 7 ml pyridine during 2 h. After 4 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. Precipitation with DIPE and filtration gives the title compound: m.p.: 204-205° C.
