実験手順
A mixture of 5-methylthio-1,3,4-thiadiazol-2-yl isocyanate dimer (0.05 mole), the dimethyl acetal of 2-propylaminoacetaldehyde (0.1 mole) 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. The residue is then recrystallized to yield the desired product the dimethyl acetal of 2-[1-propyl-3-(5-methylthio-1,3,4-thiadiazol-2-yl)ureido] acetaldehyde.
