実験手順

205 mg (1.13 mmol) of C-(5-methylfuran-2-yl)-C-(3-methyloxetan-3-yl)methylamine in solution in 3 ml of methanol were added to a suspension of 249 mg (0.75 mmol) of 3-[2-hydroxy-3-(morpholine-4-carbonyl)phenylamino]-4-methoxycyclobut-3-ene-1,2-dione in 22 ml of methanol. The reaction medium was then heated at 50° C. for two hours and stirred at ambient temperature for 3 days. The reaction medium was concentrated. The residue was taken up with ethyl acetate and was washed twice with a 1 M aqueous sodium dihydrogen phosphate solution. The organic phase was dried over anhydrous sodium sulfate, filtered and concentrated. The residue was chromatographed on silica gel (25 g prepacked column: eluent heptane/ethyl acetate from 80% to 100% of ethyl acetate). 0.23 g of product were obtained in the form of a yellow solid. Yield=64%, HPLC purity=98.01%
