Reaction Steps

To a stirred solution of 4-cyanophenyl isocyanate (0.400 g, 2.78 mmol) in 5 mL of acetonitrile was added a solution of aminomethylsulfonic acid (0.308 g, 2.77 mmol) and sodium hydroxide (0.111 g, 2.78 mmol) in 1.5 mL of water. The reaction mixture was stirred for 4 days, then concentrated in vacuo. The residue was slurried in water, and filtered. The filtrate was concentrated in vacuo, slurried in acetonitrile and filtered to afford 0.67 g (99%) of crude product. The crude product was purified by recrystallization from ethanol/water to afford 0.423 g (62%) of the desired urea. Analytical results are given below.
