実験手順
Compound (1) (0.67 g, 5.5 mmol) and EDC (1.1 g, 5. 7 mmol) was dissolved in dimethyl sulfoxide (DMSO) (10 mL). N,N-dimethyl 1,2-ethylenediamine [compound (2)] (7.5 mL, 5.7 mmol) was added and the mixture was stirred at room temperature for 5 hours, whereafter the reaction mixture was freeze dried. The residue was subjected to column chromatography [silicon dioxide (SiO2) plates chromatographed in chloroform (CHCl3)-methanol (30:1, v/v)+triethylamine (Et3N) (1:1, v/v). This procedure gave quantitative yield (1.1 g) of compound (3) as a syrup.
