该中间体在本合成路线中的序号:(IV)Maltol (I) was protected as the benzyl ether (II) by means of benzyl chloride, and subsequently treated with 1-(2-aminoethyl)piperidine (III) in refluxing ethanol to produce the substituted pyridone (IV). The benzyl protecting group of (IV) was finally removed with boron tribromide, yielding the title hydroxypyridone, which was isolated as the dihydrobromide salt.
