Procedure
A mixture of 5-cycloheptyl-1,3,4-thiadiazol-2-yl isocyanate dimmer (9.5 grams), the dimethyl acetal of 3-methylaminopropionaldehyde (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 3-[1-methyl-3-(5-cycloheptyl-1,3,4-thiadiazol-2-yl)ureido]propionaldehyde.
