실험 절차

A mixture of 2.53 gm (0.01 mol) of (E)-2-[(amino)phenylmethylene]-benzo[b]thiophen-3(2H)-one, 40.0 gm (0.44 mol) of methylammonium acetate and 10 ml of dimethylsulfoxide was heated for 5 hours to a reaction temperature of 130° to 140° C. Working up was in accordance with Example 65, and the desired compound, m.p. 154°-155° C. (methanol), was obtained with a yield of 58% of theory. The product was identical to that of Example 2 according to elemental analysis and thin-layer chromatogram.
