3-Allylaminopropionaldehyde → 3-[1-Allyl-3-(5-methylsulfonyl-1,3,4-thiadiazol-2-yl)ureido]propionaldehyde

Participants

Reaction Steps

A mixture of 5-methylsulfonyl-1,3,4-thiadiazol-2-yl isocyanate dimer (0.05 mole), the dimethyl acetal of 3-allylaminopropionaldehyde (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 3-[1-allyl-3-(5-methylsulfonyl-1,3,4-thiadiazol-2-yl)ureido]propionaldehyde.
