Development of a scalable process for 1-(3,5-dichlorophenyl)-5-iodo-3- methyl-(4-methylbenzyl)-1H-imidazo[1,2-a]imidazol-2-one: A key intermediate for the synthesis of LFA-1 inhibitors

A safe, robust, chromatography-free and reproducible process for the multi-kilogram synthesis of vinyl iodide 2, a key intermediate for the synthesis of LFA-1 inhibitors, was developed and implemented at the pilot plant. Execution of the above process all

Regiocontrolled synthesis of highly-functionalized fused imidazoles: A novel synthesis of second generation LFA-1 inhibitors

A new and reliable route to a new class of LFA-1 inhibitors such as (2) has been developed. A key aspect of this route is the transformation of amino amide 5 into iodide 3 in four steps. Iodide 3 is a key advanced intermediate used in the synthesis of all
