A mixture of 5-(4-chlorocyclohexyl)-1,3,4-thiadiazol-2-yl isocyanate dimer (13 grams), the dimethyl acetal of 2-ethylaminoacetaldehyde (6.9 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. The residue is then recrystallized to yield the desired product the dimethyl acetal of 2-{1-ethyl-3-[5-(4-chlorocyclohexyl)-1,3,4-thiadiazol-2-yl]ureido}acetaldehyde.
