文摘

A practical and scalable route to the Wnt inhibitor SEN461 1 is described herein. The optimized route consists of nine chemical steps. The intermediates are solids and were isolated by filtrations. Critical reactions steps in the medicinal chemistry route were modified for an initial scale-up process, and as a result, we developed a synthetic procedure for the preparation of multihundred gram quantities of the final product. A further process development for the phase 1 clinical batch campaign is reported.
