合成路线1
该中间体在本合成路线中的序号：(IV)The title compound has been synthesized by two related methods. Coupling of N-Boc-L-methylhistidine (I) with D-4-methoxyphenylalanine methyl ester (II) employing EDC/HOBt affords the protected dipeptide (III). Subsequent saponification of the methyl ester (III) leads to carboxylic acid (IV). This is then coupled to 4-butyryl-4-phenylpiperidine (V) to furnish amide (VI). Finally, acidic cleavage of the N-Boc protecting group of (VI) provides the title compound.
