该中间体在本合成路线中的序号：(II)Treatment of chromane (I) with metanesulfonyl chloride in pyridine at 0 C afforded mesylate (II), which was treated with 2-methylaminoethanol (III) to afford tertiary amine (IV). Reaction with SOCl2 gave chloride (V), and further reaction with p-hydroxybenzaldehyde (VI) provided (VII). Aldehyde (VII) was then condensed with 2,4-thiazolidinedione (VIII) in the presence of piperidine benzoate in toluene to furnish (IX). Finally, the benzyl protecting group was removed by treatment with acetic acid-hydrochloric acid at 60 C to give the title compound.
