该中间体在本合成路线中的序号:(I)The thiocarbamoylation of the thiophenesulfonamide (I) with isopropyl isothiocyanate in the presence of potassium tert-butoxide furnished the sulfonyl thiourea (II). This was cyclized to the thienothiadiazine derivative (III) upon treatment with phosgene and triethylamine in cold THF. The acetyl group of (III) was finally removed by hydrolysis with NaOH.
