2-Propargylamino-3-methoxypropionaldehyde → 2-[1-Propargyl-3-(5-hexyl-1,3,4thiadiazol-2-yl)-ureido]-3-methoxypropionaldehyde

Participants

Reaction Steps

5-Hexyl-1,3,4-thiadiazol-2-yl isocyanate dimer (0.05 mole), the dimethyl acetal of 2-propargylamino-3-methoxy-propionaldehyde (0.1 mole) and benzene (60 ml) are charged into a glass reaction vessel equipped with a mechanical stirrer, thermometer and reflux condenser. The reaction mixture is heated at reflux for a period of about 30 minutes. After this time the mixture is stripped of benzene under reduced pressure to yield a solid product as the residue. This residue is then recrystallized to yield the desired product the dimethyl acetal of 2-[1-propargyl-3-(5-hexyl-1,3,4thiadiazol-2-yl)-ureido]-3-methoxypropionaldehyde.
