Reaction Steps

To a solution of furo[2,3-c]pyridazin-5(6H)-one O-methyl oxime (1.35 mmol) in 10 mL 7N NH3 in MeOH was added Pd/C (50 mg) and the reaction mixture was stirred under a H2 atmosphere for 1 h. The mixture was then filtered over Celite, washed with 20 mL MeOH and concentrated in vacuo to give the title compound as dark red oil;
