Starting material Iv: theta-chloro-lambda^-ethylpyridazine-S^-diamineSM Iv was prepared in 5 steps from commercially available 3-chlorofuran-2,5-dione EPO Step 1: 4-chloro-l,2-dihydropyridazine-3,6-dione:To a solution of 3-chlorofuran-2,5-dione (1Og) in EtOH(200 mL) was added hydrazine monohydrate (4 mL) and refluxed for 10 h. The reaction mixture was concentrated to yield 4- chloro-l,2-dihydropyridazine-3,6-dione, which was used directly in the next step. M/Z 146.
