Reaction Steps

To a stirred solution of 2,4-difluoronitrobenzene (3.18 g., 20 mmole) In DMSO (5 ml) was added portion-wise N,N-dimethylethylene-diamine (3.52 g., 40 mmole). The mixture was stirred at 23° C. for 1 hour and poured into crushed ice. Ethyl acetate (200 ml) was added to dissolve the orange-yellow solid. The organic phase separated was washed with water and brine, dried over sodium sulfate and evaporated under reduced pressure. The residue was chromatographed on a silica gel column eluting with CH2Cl2 /MeOH (20:1) to afford the compound (15) (2.8 g., 62%) which solidified on standing.
