Procedure: 12.5 g (50 mmol) of ethyl 10-thia-1,4-diazatricyclo[6.3.0.02,6 ]undecane-4-carboxylate are heated under reflux overnight with 32 g of Ba(OH)2.8H2O in 225 ml of water. Potassium carbonate is added to the mixture, barium carbonate is filtered off with suction and the filtrate is extracted ten times using 100 ml of chloroform each time. The extracts are dried over potassium carbonate and concentrated, and the residue is distilled. is filtered off with suction the filtrate is extracted ten times The extracts are dried over potassium carbonate concentrated the residue is distilled

Procedure: 12.5 g (50 mmol) of ethyl 10-thia-1,4-diazatricyclo[6.3.0.02,6 ]undecane-4-carboxylate together with 32 g of Ba(OH)2 ×8H2O are refluxed overnight in 225 ml of water. Potassium carbonate is added, barium carbonate is filtered off with suction, and the filtrate is extracted ten times using 100 ml portions of chloroform. The extracts are dried over potassium carbonate, concentrated and distilled. barium carbonate is filtered off with suction the filtrate is extracted ten times The extracts are dried over potassium carbonate concentrated distilled
