5-(1-Aminoalkyl)-3-methoxycarbonyl-1-phenyl-1H-1,2,4-triazoles 5 were prepared from N-benzyloxycarbonyl-protected α-amino acids by reaction of the corresponding mixed anhydrides 2 with methyl phenylhydrazono(triphenylphosphoranylideneamino)acetate (3) and subsequent deprotection.
5-(1-氨基烷基)-3-甲氧基羰基-1-苯基-1H-1,2,4-三唑5是由N-苄氧基羰基保护的α-氨基酸通过相应的混合酸酐2与甲基苯腙反应制备的(三苯基正膦基氨基)乙酸酯(3)和随后的脱保护。
