Reaction Steps

To a solution of 6-[(4-chlorobenzyl)sulfanyl]-3,4-bis[(4-methoxybenzyl)oxy]pyridazine (Intermediate 8; 527 mg, 1.04 mmol) in methanol (5177 μl) was added a solution of hydrogen chloride in dioxane (4.0 M, 5177 μl, 20.71 mmol) and the reaction was allowed to stir at room temperature for 72 hours. The resulting mixture was concentrated in vacuo to afford a yellow solid which was recrystallised from ethanol to afford 6-[(4-chlorobenzyl)sulfanyl]-4-hydroxypyridazin-3(2H)-one as white crystals (153 mg, 56.9 mmol, 55%).
