実験手順

To a solution of 3-tert-butyl-4-hydroxyphenylalanyl (2-pyridyl)amide (1.48 g, 4.73 mmol), Z-N-Me-Val-OH (1.63 g, 6.15 mmol) and CMPI (1.57 g, 6.15 mmol) in THF 30 ml, TEA (1.5 ml, 10.88 mmol) was added under cooling with ice and stirred for 3 hours under cooling with ice. The mixture was mixed with water and extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and evaporated to remove the solvent under reduced pressure; the thus obtained residue was subjected to silica gel column chromatography (developing solvent: ethyl acetate:n-hexane=1:2), giving the titled compound (1.74 g, 65%).
