Reaction Steps

To a solution of 3-(4-chloro-1,2,5-thiadiazol-3-yl)-1,2,5,6-tetrahydro-1-methylpyridine (670 mg, 3.1 mmol) in 1,2-dichloroethane (20 ml) was added a solution of 1-chloromethyl-chloroformate (440 mg, 3.1 mmol) in 1,2-dichloroethane at 0° C. The reaction mixture was heated to 40° C. for 2 h and evaporated. The residue was dissolved in methanol and heated to reflux for 1 h. After cooling to room temperature the precipitate was collected by filtration to yield 320 mg (41%). (M.p. 224° C.; M+ : 201 and 203; Compound 17).
