Procedure
A solution of the product obtained in Step 2 (1.5 g) in 50 ml of methanol was cooled to 0° C., 24 ml of thionyl chloride was added by dropwise to this solution at that temperature, and the mixture was refluxed for 1.5 hours. After removing the solvent by distillation under reduced pressure, the residue was recrystallized from ethyl acetate/ether, giving 1.5 g of the objective compounds.
