Reaction Steps

There were mixed, each in a powdery state, 500 mg of 6-[2-(3,4-dimethoxybenzoylamino)acetyl]-3,4-dihydrocarbostyril and 2,4-bis(4-methoxyphenyl)-1,3-dithia-2,4-diphosphetane-2,4-disulfide (Lawesson's reagent). The mixture was stirred at 200° C. with heating. After 3 hours, the reaction was completed. The residue was subjected to silica gel column chromatography (dichloromethane:methanol=49:1 by v/v). A solid obtained from the eluate was recrystallized from ethanol to obtain 98 mg of 2-(3,4-dimethoxyphenyl)-5-(3,4-dihydrocarbostyril-6-yl)thiazole as a white powder.
