実験手順

A solution of 5 gm (29 mMol) 6-chloro-3-nitro-2-picoline in 40 mL dimethylformamide was treated with 5.83 mL (44 mMol) dimethylformamide dimethylacetal and the resulting mixture heated at 100° C. for 1.5 hours. At this point, 2 drops of triethylamine followed by 1.9 mL dimethylformamide dimethylacetal were added and heating continued for 2 more hours. The reaction mixture was concentrated under reduced pressure to provide the desired compound.
