合成路线1
该中间体在本合成路线中的序号：(XIV)Coupling of the amine (XII) with N-Boc-2-aminoisobutyric acid (XIII) leads to the dipeptide amide (XIV). Alkaline hydrolysis of the ethyl ester group of (XIV) gives the benzoic acid (XV), which is then coupled to ethylamine to produce the amide (XVI). Finally, the N-Boc protecting group of (XVI) is cleaved by means of HCl in dioxane to furnish the target compound.
