该中间体在本合成路线中的序号：(IV)In an improved method, the acetamido isophthalamide (I) is treated with boric acid and KOH to form the cyclic diborate tripotassium salt (II). Subsequent alkylation of (II) with 1-chloro-3-methoxy-2-propanol (III) yields regioselectively the N-alkylated acetamide (IV). The borate groups of (IV) are finally removed upon quenching with diluted HCl.
