合成路线2
该中间体在本合成路线中的序号：(IV)The cyclization of the amino group of 4-amino-3-(4-chlorophenyl)butyric acid (I) with 2,5-dimethoxytetrahydrofuran (II) by means of AcOH in THF gives the corresponding pyrrole (III), which is cyclized by means of TEA, ClCOOEt, pyrrolidine and POCl3 in toluene yielding the pyrrolopyridone (IV). Finally, this compound is condensed with pyridine-4-carbaldehyde (V) by means of tetrabutylammonium bisulfate and NaOH in water.
