Reaction Steps
A mixture of 3-cyanophenyl isocyanate (3.76 g, 26.1 mmol) and 4-bromoaniline (4.5 g, 26.1 mmol) in 1:1 tetrahydrofuran:chloroform (100 mL). After 72 h at ambient temperature, product was isolated by filtration, the filtrate was washed with cold chloroform and air dried to give 6.6 g of N-(3-cyanophenyl)-N'-(4-bromophenyl)urea (21 mmol).
