実験手順

0.4 g (1.8 mmol) of 4-chloro-6-fluoro-3-nitro-quinoline (Example 19c) and 0.17 ml (1.98 mmol) 2-fluoroaniline in 5 ml acetic acid are stirred overnight at rt. Crystals are formed. The mixture is poured into water, the solid material is filtered off and washed with water. The residue is dissolved in CH2Cl2 and washed twice with water. The organic phase is dried over MgSO4 and most of the solvent is evaporated. The title compound is obtained from this solution as yellow crystals by adding hexane. The compound is filtered off, washed with hexane and dried (70° C., high-vacuum). mp: 161-162° C.; MS: 302 (M++1); HPLC: tret=10.24 min (Grad 1).
