Participants

Reaction Steps

10.8 g (0.04 mol) of 2-(4-cyanophenylureido)-5-aminophenol was added to 100 ml of acetonitrile and to which were added 17.6 ml (0.2 mol) of pyridine and 0.3 ml of nitrobenzene while cooling with stirring. To the solution was added dropwise 5.0 g (0.048 mol) of methacrylic chloride and the mixture was stirred for about 1.5 hours. 200 ml of water was added to the reaction mixture and the crystals thus deposited were collected by filtration and recrystallized from acetone to obtain 3.8 g (28.3%) of Monomer Coupler (18).
