반응 단계
p-Chloromethylphenylglycine wherein the amino group is protected with tert-butoxycarbonyl is treated with isobutylchloroformate in the presence of triethylamine. The thus obtained anhydride is reacted with the triethylamine salt of 3-[(2-methyl-1,3,4-thiadiazol-5-ylthio)methyl]-7-amino-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid at 0° C for about 4 hours. The resulting product is isolated, and the amine protecting group is removed by acid hydrolysis and the amine protecting group is removed by acid hydrolysis to give 3-[(2-methyl-1,3,4-thiadiazol-5-ylthio)methyl]-7-[[2-[4-(chloromethyl)phenyl]-2-aminoacetyl]amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid.
