Processes for preparing 6-(difluoromethoxy)[1]benzofuro[3,2-c]pyridine-9-carbaldehyde, a novel intermediate for the synthesis of PDE IV inhibitors

The present invention relates to novel processes for preparing 6-(difluoromethoxy)[1]benzofuro[3,2-c]pyridine-9-carbaldehyde, which is a novel and useful intermediate for preparing compounds with PDE4 inhibitory activity, such as 3,5-dichloro-4-(6-difluoromethoxybenzo[4,5]furo[3,2-c]pyridin-9-ylcarb...
