Reaction Steps

A mixture of 10-(benzyloxy)-2-(4-fluorobenzyl)-4-hydroxy-8-methyl-7,8-dihydropyrazino[1′,2′:1,5]-pyrrolo[2,3-d]pyridazine-1,9(2H,6H)-dione (23 mg, 0.05 mmol) and Pearlman's catalyst [25 mg, 20% Pd(OH)2 on carbon] in methanol (10 mL) was stirred under an atmosphere of hydrogen gas (1 atm) at room temperature for 45 minutes. The reaction mixture was diluted with acetonitrile and filtered. The filtrate was concentrated under vacuum, and the residue was subjected to purification on reverse phase HPLC. Collection and lyophilization of appropriate fractions provided the titled compound.
