合成路线1
该中间体在本合成路线中的序号：(XL)In a further procedure, epoxide (XXXII) was condensed with ethanolamine (XXXIX) to afford amino diol (XL). Coupling of (XL) with carbamate (IX) produced the N-(hydroxyethyl)urea (XLI). Chlorination of the primary hydroxyl group of (XLI) with POCl3, followed by cyclization in the presence of Et3N, gave rise to the title imidazolidinone. Alternatively, amino diol (XL) was coupled with 4-nitrophenyl isocyanate (XXXV) to give urea (XLII). Chlorination of (XLII), followed by cyclization in the presence of Et3N, produced imidazolidinone (XLIII). The tetrazolyl group of the target compound was then introduced by catalytic hydrogenation of the nitro group of (XLIII), followed by treatment with NaN3 and triethyl orthoformate.
