Procedure

A solution of potassium carbonate (0.2 g) in water 2 mL) is added to a solution of 6-acetoxymethyl-3,4-dimethoxypyridazine (0.27 g) in methanol (6 mL) and the mixture stirred at 60-70° C. for 2 hours. After evaporating to dryness the residue is partitioned between ethyl acetate (10 mL) and brine (10 mL). The ethyl acetate phase is evaporated to dryness and the residue purified by flash chromatography (ethyl acetate as eluent on silica) to give 3,4-dimethoxy-6-hydroxymethylpyridazine as a white solid, m.p. 151-3° C.
