Reaction Steps

A mixture of 2,2-dimethyl-1-[2-(3,4,5-trimethoxy-phenyl)-5H-pyrrolo[2,3-b]pyrazin-7-yl]-pent-4-en-1-one (0.036 g, 0.091 mmol), 3 mL of ethanol (a small amount of methanol was also added to help solubility) and 10% Pd/C (10 mg) was stirred under a hydrogen atmosphere (balloon) for 3 d, then filtered through Celite and concentrated to afford 0.019 g (53%) of 2,2-dimethyl-1-[2-(3,4,5-trimethoxy-phenyl)-5H-pyrrolo[2,3-b]pyrazin-7-yl]-pentan-1-one as a yellow solid.
