Yield: 92%
Reaction Conditions:
with acetic acid in water at 20; for 1 h;
Steps:
4 General synthesis of arylurea analogues (4a-m)
General procedure: The procedure was performed adopting literature.46 To a solutionof ArNH2 (3, 5 mmol, dissolved in 10 mL acetic acid), wasadded aquatic solution of NaOCN (7.5 mmol, 7.5 mL). The mixturewas allowed to be stirred at room temperature for 1 h and thenconcentrated under reduced pressure. Afterwards, saturatedK2CO3 solution was added to adjust the pH to 7-8. A large scaleof precipitate was therefore formed, which was then filtered,washed with water for several times and then recrystallized fromMeOH - DCM
