Abstract

A convenient and scalable four-step novel route has been developed for the synthesis of rosiglitazone (8), an antidiabetic drug. This multistep route requires 4-fluoro benzaldehyde (4), 2, 4-thiazolidinedione (6) and 2-chloro pyridine (1) as key reactants and gives overall better yield of rosiglitazone. In addition, some steps have been accelerated, which leads to an overall time saving of 10h.
