该中间体在本合成路线中的序号：(XII)The intermediate sulfonyl chloride (VIII) has been obtained as follows: The reaction of phenacyl bromide (X) with sodium azide in hot DMF gives the azide (XI), which is condensed with 3-cyclopentylpropionyl chloride (XII) by means of LDA yielding the enol ester (XIII). The cyclization of (XIII) by means of triethyl phosphite in refluxing hexane affords 2-(2-cyclopentylethyl)-5-phenyloxazole (XIV), which is finally sulfonated with chlorosulfonic acid to afford the target sulfonyl chloride (VIII).
