실험 절차

544 mg (3 mmol, 1.5 eq) of C-(5-methylfuran-2-yl)-C-(3-methyloxetan-3-yl)methylamine were added to 693 mg (2 mmol, 1 eq) of 3-ethoxy-4-[2-hydroxy-3-((R)-3-hydroxypyrrolidine-1-carbonyl)phenylamino]cyclobut-3-ene-1,2-dione dissolved under hot conditions in 30 ml of methanol. The reaction medium was heated at 50° C. for 3 days and then at 60° C. for 5 hours. The methanol was evaporated off and the residue was chromatographed on silica gel (column puriFlash IR-50SI/80G, Spot II) then subsequently on silica gel (column puriFlash PF-15SIHP/25G×2, Spot II) eluted with dichloromethane/methanol (gradient). 694 mg of 3-[2-hydroxy-3-((R)-3-hydroxypyrrolidine-1-carbonyl)phenylamino]-4-{[(5-methylfuran-2-yl)-(3-methyloxetan-3-yl)methyl]amino}cyclobut-3-ene-1,2-dione were obtained in the form of an orange amorphous solid. Yield=72%. LC/MS: 99.6% [481].
