Development of a suitable process for the preparation of a TNF-α converting enzyme inhibitor, WAY-281418

A suitable process for the preparation of kilogram quantities of a TNF-α converting enzyme (TACE) inhibitor (WAY-281418) was developed using isatin 13 as starting material and an efficient coupling step for the formation of sulfonamide 8 in a 15% overall yield. Process preparation of (+)-(1S,2R)-2-aminocyclopentane-1-carboxylic acid (7, (+)-cispentacin), a chiral component for WAY-281418, was successfully scaled up via an asymmetric hydroge-nation reaction. Crystallization allowed the isolation of all intermediates and the final product 9.
