실험 절차

To a solution of 1 g of 4-{(S)-4-tert-Butoxycarbonyl-2-[(4-hydroxy-7-methyl-quinoline-2-carbonyl)-amino]-butyryl}-piperazine-1-carboxylic acid ethyl ester and 341 mg of (S)-2-Hydroxy-propionic acid benzyl ester in 15 ml of THF, 744 mg of Triphenyl-phosphane and 494 mg of Diethyl azodicarboxylate was added and stirred for 2 h. Then, the reaction mixture was diluted with water and extracted with ethyl acetate. 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: 1.0 g.
