Participants

Reaction Steps

To 2-amino-5,6-dimethoxybenzonitrile (3.4 g, 19.0 mmol) dissolved in 50 ml of benzene, was added 30 mmol of methylisocyanate in benzene. The resultant mixture was refluxed for 0.75 hours and the tan precipitate which formed was collected by filtration. Recrystallization of the crude product from 2-propanol gave 1.59 g (34%) of the analytical urea, mp 236°-237.5°.
