실험 절차

To a solution of 1.3 g of 5-Hydroxy-1-phenyl-1H-pyrazole-3-carboxylic acid and 2.2 g of 4-((S)-2-Amino-4-tert-butoxycarbonyl-butyryl)-piperazine-1-carboxylic acid ethyl ester in 80 ml of DMF, 0.9 g of HOBT and 1.3 g of EDC was added and the reaction mixture was stirred for 2 h at RT. Then, the reaction mixture was diluted with water and extracted with DCM. The organic phase was dried over MgSO4 and the solvents were removed under reduced pressure. The crude product was purified by chromatography on silica gel eluting with a gradient of n-heptane/ethyl acetate. The fractions containing the product were combined and the solvent evaporated under reduced pressure. Yield: 2.7 g.
