Participants

Reaction Steps

A mixture of 1-(5-methyl-pyrazin-2-yl)-piperidin-4-ol (500 mg) and Dess-Martin periodinane (1.30 g) in dichloromethane (20 mL) is stirred at room temperature for 4 h. Aqueous Na2S2O3 solution and NaHCO3 solution are added and the organic phase is separated, washed with brine, dried over MgSO4 and concentrated in vacuo. The residue is triturated with a small amount of methanol. The mixture is filtered and the filtrate is concentrated in vacuo to give the title compound. LC (method 1): tR=0.56 min; Mass spectrum (ESI+): m/z=192 [M+H]+.
