実験手順

A mixture of 4-chloro-3-iodo-1-methyl-5-phenyl-1H-pyrazolo[3,4-c]pyridazine (1.5 g, 4.05 mmol) and NaOH aqueous solution (4 M, 2 mL) in DMSO (6 mL) and dioxane (6 mL) was heated to 50° C. for 2.5 h. The mixture was left to cool to rt, then neutralised to pH 2-3, when a precipitate formed. The solid was filtered, washed with water and dried, to give 1.33 g of the intermediate.
