実験手順
3-(Chloromethyloxymethyl)-1,2,5-thiadiazole Sulfuryl chloride (0.24 mmol) in dry dichloromethane (0.5 ml) was added dropwise over a period of 3 minutes at 0° C. to a solution of 3-(Methylthiomethyloxy)methyl-1,2,5-thiadiazole (0.24 mmol) in dry dichloromethane (1.5 ml). The mixture was stirred at 0° C. for 5 minutes and at room temperature for 10 minutes before the solution was evaporated at reduced pressure. The crude product (30 mg, 75%) was used for alkylation in Example 9 without any further purification.
