Procedure
100 mg (4.0 mmol) of sodium were added to ethanol (20 ml). After reaction of the sodium was complete, 500 mg (2.0 mmol) of 1-(3-methanesulfonyl-[1,2,4]-thiadiazol-5-yl)piperazine were added and the mixture was subsequently stirred at 50° C. 2 h. The cooled reaction solution was poured into a satd aq. NaCI soln cooled to 0° C. This mixture was extracted with EA. The organic phase was dried over MgSO4, filtered and concentrated in vacuo. 310 mg (1.54 mmol, 77%) of 1-(3-methoxy-[1,2,4]-thiadiazol-5-yl)piperazine were obtained.
