该中间体在本合成路线中的序号：(XIV)In an alternative synthetic procedure, dinitrile (VII) was cyclized in the presence of sodium methoxide to produce 6-amino-8-methoxy-1,7-naphthyridine (XII). This was converted to triflate (XIII) by diazotization in the presence of trifluoromethanesulfonic acid. Suzuki coupling of triflate (XIII) with 4 carboxyphenylboronic acid (XI) yielded adduct (XIV). The 8-methoxy group of (XIV) was then displaced with PBr3 to produce bromide (XV), which was subjected to further Suzuki coupling with the benzofurazan boronic acid (V) to provide the title compound.
