Participants

Reaction Steps

To a solution of 2 g. of 5-amino-2-nitro-3-phenylbenzofuran in 100 ml. of hot benzene is added 4 ml. of n-propyl isocyanate. The mixture is heated on a steam bath for 30 minutes, then evaporated to dryness. The residue is recrystallized from aqueous methanol to provide orange crystals of 2-nitro-3-phenyl-5-(n-propyl)ureidobenzofuran, m.p. 199°-201° C., having the structure ##STR21##
