Reaction Steps
A mixture of 6-Difluoromethyloxybenzo[4,5]furo[3,2-c]pyridine-9-carboxylic acid (5.5 g, 0.0197 moles), p-nitro phenol (4.1 g, 0.0295 moles), EDCl (5.7 g, 0.295 moles), 4,4-dimethyl amino pyridine (250 mg, 0.00197 moles) in DMF (603.0 mL) was heated to 70-75° C. for 4-5 hours. The residue obtained after removal of solvent under vacuo was triturated with water (50.0 mL) to give intermediate-18 (6.0 mg) as yellow solid.
