실험 절차

300 ml in dichloromethane of 11.35 g of 5-ethoxy-2-(4-hydroxyphenylthio)-7-isopropoxy-6-methoxychromone obtained in Example 18, 5.43 g of N-t-butoxycarbonyl(Boc)glycine, and 6.40 g of dicyclohexylcarbodiimide (DCC) was stirred over 5.5 hours at room temperature. The solution thus reacted was gravitationally filtered. The solvent was distilled out from the filtrate, so that N-t-butoxycarbonyl(Boc)glycine ester was obtained. This product was dissolved in 100 ml of ethyl acetate. Then, hydrochloric acid gas was introduced and bubbled in the solution for 10 min., followed by stirring for 1 hour. Subsequently, 200 ml ether was added and the resulting crystals were collected by filtration and dried, whereby 11.28 g of 5-ethoxy-2-(4-glycyloxyphenylthio)-7-isopropoxy-6-methoxychromone hydrochloride with the following physicochemical properties was obtained.
