実験手順
A solution under nitrogen was prepared from 10.7 g of the compound produced in Example 1 and 3.95 g of thiourea in 200 ml of ethanol. After refluxing the solution four hours, it was allowed to stir at room temperature overnight. The solvent was removed under reduced pressure. Then, the residue was triturated with hexane to give 16 g of solid (wet weight), m.p. 175°-180° C.
