Reaction of carbamate with DMF gives rise two isomers .The process was followered employing the NMR technique,removing samples in different time in tervals. The percentage yields were obtained and potted vs time exhibting a logarithmic reaction ship. isomer (B) .scheme appears to be more, stale due to resonance factors.Although isomer (A) is kinethically more feasible . Spectral analysis is in accord with the above propositions
