Reaction Steps

5-Aminospiro[benzo[b]furan-2(3H),1'-cyclopropane]-3-one (1.75 g.) and methyl isocyanate (1 ml.) were stirred in tetrahydrofuran for 2 hours at room temperature. The solvent was evaporated off under reduced pressure, and the residue was recrystallized from ethanol to give yellow prisms of 5-methylureidospiro[benzo[b]furan-2(3H),1'-cyclopropane]-3-one (1.06 g.).
