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.
