Procedure

3-Hydroxyquinoline (I) (prepared according to the procedure of Naumann et. al., Synthesis 4:279–281 (1990)) (3 g) and 1,2,3-trichloro-5-nitrobenzene (4.7 g) were dissolved in DMF (80 mL) and heated with cesium carbonate (7.4 g) for 2 h at 60° C. The reaction was poured into ice/water (500 mL). The resulting off-white precipitate was collected by filtration and rinsed with hexane to afford compound II as a solid (6.9 g) suitable for use in the next reaction.

Workup

  1. filtrationThe resulting off-white precipitate was collected by filtration
  2. washrinsed with hexane
