5-Methoxy-1,3,4-thiadiazol-2-yl isocyanate → HCID 53653296, compound

Participants

Reaction Steps

5-Methoxy-1,3,4-thiadiazol-2-yl isocyanate dimer (0.05 mole), the dimethyl acetal of 2-β-chloroethylamino-3-methoxypropionaldehyde (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-β-chloroethyl-3-(5-methoxy-1,3,4-thiadiazol-2-yl)ureido]-3-methoxypropionaldehyde.
