合成路线1
该中间体在本合成路线中的序号：(X)Isocyanate (XI) was prepared by treatment of tert-butyl 3-aminobenzoate (X) with triphosgene and triethylamine. Coupling of isocyanate (XI) with amine (IX) gave rise to the urea (XII). The lactam N of (XII) was then alkylated with bromomethyl tert-butyl ketone (XIII) in the presence of K2CO3 and tetrabutylammonium bromide to give (XIV). Cleavage of the tert-butyl ester group of (XIV) with trifluoroacetic acid yielded the carboxylic acid (XV), which was finally isolated as the corresponding calcium salt.
