Hydrochloric Acid → Methyl 3-(6-aminopyridazin-4-yl)benzoate

Participants

Reaction Steps

1.0 M HCl (2.0 mL) was added to a solution of methyl 3-{6-[(diphenylmethylene)amino]pyridazin-4-yl}benzoate (0.16 g, 0.40 mmol) in THF (4.0 mL) and then the reaction was stirred at r.t. for 1.5 h. The mixture was carefully neutralized with Na2CO3 (2.0 eq) and then concentrated under reduced pressure to give the crude product (0.20 g) which was directly used in the next reaction without further purification. LCMS (M+H)+: m/z=230.1
