2-(3,6-dihydro-2H-pyran-4-yl)-3-fluoropyrazine → 2-fluoro-3-(Tetrahydro-2H-pyran-4-yl)pyrazine

Participants

Reaction Steps

To a round-bottomed flask was added 2-(3,6-dihydro-2H-pyran-4-yl)-3-fluoropyrazine (1.1754 g, 6.52 mmol) and palladium hydroxide on carbon (0.458 g, 0.652 mmol) in EtOAc (21.75 mL). The reaction mixture was flushed with argon and then placed under vacuum three times. A hydrogen balloon was then attached to the reaction. After stirring overnight, the reaction mixture was filtered through celite and concentrated in vacuo to give the title compound. MS (ESI, pos. ion) m/z: 183.1.
