合成路线1
该中间体在本合成路线中的序号：(II)Addition of formaldehyde to 5,7-dichlorobenzothiophene-2-sulfonamide (I), followed by condensation with trimethyl phosphite, furnished the dimethyl (sulfonamidomethyl) phosphonate (II). The phosphonate ester function of (II) was then hydrolyzed by means of bromotrimethylsilane, producing phosphonic acid (III). This was finally coupled to 4-nitrophenol (IV) using trichloroacetonitrile in hot pyridine to afford the title mono-phosphonate ester.
