Procedure
0.135 mole = 44 g of 7-benzyloxy-1-(1,3-dithia-2-cyclopentyl)-heptane-3-one were heated for 1 hour under nitrogen and under reflux in 1 liter of acetone with [0.275 mole] = 47 g of CuCl2. 2 H2O and [0.57 mole] = 44 g of CuO, the copper salts were filtered off and the filtrate was concentrated under reduced pressure. The residue was dissolved in ether, washed twice with 2N- HCl and thrice with water, dried and the solvent was removed by distillation under reduced pressure. The residue was distilled under reduced pressure. B.p.0.5 mm 185°-192° C.
