実験手順

To stirring phosphorous oxychloride (87 ml) at 80° C. was added four 2.0 g portions of 6-phenylsulfonyl-3-oxo-2,3-dihydropyridazine every 30 minutes. After additional two 1.0 g portions were added with stirring, the reaction mixture was slowly poured into ice-water over 1 hour to form the precipitate, which was collected, washed well with water, and dried to give 6-chloro-3-ph-enylsulfonylpyridazine (8.4 g).
