Reaction Steps
Add 250 g (1.2 mol) of the product from Example XVIII to a solution of 75 g (2.3 mol) of sulfur in 1.5 liters of decalin and heat to 180-190° C. under nitrogen for 6 hr. Cool to room temperature and extract with 2-1.5 liters of 2N sulfuric acid. Combine the acid extracts and make basic with potassium hydroxide, then wash with 2×1 liter of methylene chloride. Combine the methylene chloride extracts, dry over sodium sulfate, treat with charcoal, and remove the solvent in vacuo. Crystallize the residue from ether to provide the title compound.
