Procedure

A mixture of 284 mg (0.87 mmol, 1 eq) of 2-hydroxy-3-(2-methoxy-3,4-dioxocyclobut-1-enylamino)-N,N-dimethylbenzenesulfonamide and 318 mg (1.75 mmol) of C-(5-methylfuran-2-yl)-C-(3-methyloxetan-3-yl)methylamine in 20 ml of methanol was heated at 50° C. for 3 days. The reaction medium was concentrated. The residue was taken up in 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. 0.29 g of product was obtained in the form of an ochre solid. Yield=70%, HPLC=98.68%, Mp=123° C.
