of o-ureidobenzonitriles, from o-aminobenzamides and isothiocyanates using T3P. Here, the conversion of thiourea to urea and amide to nitrile take place simultaneously via unprecedented intramolecular rearrangement. This protocol is operationally facile and offers wide variety of o-ureidobenzonitriles at room temperature in good to excellent yields.
