Novel and efficient process for the synthesis of 1,3,4-oxadiazole containing MBX-4132 as antimicrobial agent in Neisseria gonorrhoeae

A novel and efficient approach to the synthesis of MBX-4132 has been reported. Having 1,3,4-oxadiazole-containing compound that inhibits trans translation process by binding to the bacterial ribosome and act as an antimicrobial agent. It involved the reaction of 5-(4-fluorophenyl)-1,3,4-oxadiazol-2-amine, with diphenyl carbonate to yield the corresponding carbamates, which in situ reacted with 1,2,3,4-tetrahydroisoquinoline to produce MBX-4132 with a comparatively higher yield (65%). The above process involves mild reaction conditions and uses nontoxic, non-hazardous, and cheaper reagents such as diphenyl carbonate as a carbonyl source thereby making the process economical and environment friendly.
