Reaction Steps

To a solution of 1 eq 1-(pyridin-2-ylmethyl)piperazine hydrochloride in dry dichloromethane are added 1.5 eq butanoyl chloride and 2.5 eq triethylamine. After stirring for 6 hours at room temperature the solvent is removed in vacuo and the residue re-dissolved in ethyl acetate. The organic solution is subsequently washed with 1 M KHSO4, 5% NaHCO3 and brine. After drying over Na2SO4, ethyl acetate is removed in vacuo and the crude product is purified by column chromatography.
