The invention relates to a Smoothened receptor ligand which antagonises the Hedgehog pathway, to pharmaceutical compositions and therapeutic applications thereof, processes for obtaining this compound and novel intermediates useful in these processes.
A practical and scalable route to the SMO receptor antagonist SEN794 1 is described herein. A new and efficient access to the key intermediate 7 via the Kröhnke reaction was developed, significantly simplifying the synthesis and reducing costs. The optimized route consists of six chemical steps plus a palladium scavenging step. The intermediates are solids and were isolated by filtrations, except for
