実験手順

A saturated solution of phosgene is ethyl acetate (100 ml) is charged into a glass reaction vessel equipped with a mechanical stirrer. A slurry of 5-chloromethyl-2-amino-1,3,4-thiadiazole (10 grams) in ethyl acetate (300 ml) is added to the reaction vessel, and the resulting mixture is stirred for a period of about 16 hours, resulting in the formation of a precipitate. The reaction mixture is then purged with nitrogen gas to remove unreacted phosgene. The purged mixture is then filtered to recover the desired product 5-chloromethyl-1,3,4-thiadiazol-2-yl isocyanate dimer as a solid.
