An easy and rapid procedure for the preparation of N-monosubstituted ureas via reaction between potassium cyanate and a wide range of amines is described. The procedure was performed undermicrowaveirradiation using water as solvent. This methodology is particularly attractive since it provides ureas in high yield and purity.
