실험 절차

A mixture of 371 mg (2.07 mmol, 1.2 eq) of C—(R)-(5-methylfuran-2-yl)-C-(3-methyloxetan-3-yl)methylamine (prepared in EXAMPLE 50, steps 1 to 4) and 600 mg (1.7 mmol, 1 eq) of methyl {[2-hydroxy-3-(2-methoxy-3,4-dioxocyclobut-1-enylamino)benzoyl]methylamino}acetate in 24 ml of methanol was heated at 60° C. for 16 hours. The methanol was evaporated off and the residue was chromatographed on silica gel, eluent dichloromethane/ethyl acetate (75/25). The paste obtained was crystallized from diethyl ether and heptane and dried under vacuum at 40° C. 660 mg of methyl {[2-hydroxy-3-(2-{[(R)-(5-methylfuran-2-yl)-(3-methyloxetan-3-yl)methyl]amino}-3,4-dioxocyclobut-1-enylamino)benzoyl]methylamino}acetate were obtained in the form of a pale yellow solid. Yield=76%.
