Participants

Reaction Steps

To a solution of (S)-1-(piperazine-1-carbonyl)-piperidine-2-carboxylic acid (5-tert-butyl-isoxazol-3-yl)-amide (60 mg; 0.165 mmol) in THF (1 mL) is added propionyl chloride (0.015 mL; 0.17 mmol), followed by N,N-diisopropylethylamine (0.03 mL; 0.17 mmol). The mixture is stirred at room temperature for 18 hours. The mixture is diluted with ethyl acetate and water. The layers are separated and the organic layer is concentrated in vacuo. Purification by flash chromatography on silica gel using ethyl acetate/Hexanes provides the title compound, m/z 420 [M+H+].
