실험 절차

A mixture of 5-chloromethyl-1,3,4-thiadiazol-2-yl isocyanate dimer (9.5 grams), the dimethyl acetal of 2-methylaminoacetaldehyde (5.8 grams) and benzene (60 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer and reflux condenser. The reaction mixture is heated at reflux for a period of about 15 minutes. After this time the mixture is stripped of benzene under reduced pressure to yield a solid product as the residue. This product is recrystallized to yield the desired product the dimethyl acetal of 2-[1-methyl-3-(5-chloromethyl-1,3,4-thiadiazol-2-yl)ureido]acetaldehyde.
