실험 절차

To a solution of 2.0 g (8.5 mmol) 2-bromo-5-chloro-4-methoxy aniline in 20 ml acetic acid and 20 ml water was added in small portions 1.37 g (17 mmol) potassium cyanate. The mixture was stirred at r.t. for 2 hours, neutralized with 2N NaOH and the product was extracted into ethyl acetate. Removal of the solvent and crystallization with ether gave 0.69 g (29%) of the desired urea.
