Reaction Steps
The residue of Step 1 was dissolved in dichloromethane. Pyridine, picolinoyl chloride hydrochloride and a catalytic amount of DMAP were added. A further addition of the reactants was made after two hours. After evaporation of the solvent, the residue was diluted with EtOAc, the organic phase washed with water, dried (Na2SO4) and evaporated to afford the title product.
