Benzene → 2-[1-Allyl-3-(5-t-butyl-1,3,4-thiadiazol-2-yl)ureido]acetaldehyde

Participants

Reaction Steps

A mixture of 5-t-butyl-1,3,4-thiadiazol-2-yl isocyanate dimer (8.7 grams), the diethyl acetate of 2-allylaminoacetaldehyde (8.0 grams) and benzene (30 ml) was charged into a glass reaction flask equipped with a mechanical stirrer and reflux condenser. The reaction mixture was heated with stirring for a period of about 15 minutes. After this time the reaction mixture was stripped of benzene to yield an oil. The oil was dissolved in a diethyl ether-pentane mixture and was filtered through diatomaceous earth. The filtrate was stripped of solvent to yield the desired product the diethyl acetal of 2-[1-allyl-3-(5-t-butyl-1,3,4-thiadiazol-2-yl)ureido]acetaldehyde as a dark oil.
