Yield: 95%
Reaction Conditions:
in dichloromethane at 20; for 1 h;
Steps:
3 Example 3: Synthesis of 1-(4-bromophenyl)-3-ethylurea (YF-3)
At room temperature, add 4-bromoisocyanate (1.2 g, 6.06 mmol) to a single-necked flask,Dichloromethane (200 mL) was stirred and dissolved, and a solution of ethylamine (0.33 g, 7.27 mmol) in 20 mL of dichloromethane was added dropwise to the reaction flask. A large amount of solid was quickly precipitated, and the stirring was continued for 1 h. Suction filtration,Obtained 1.40 g of white solid, yield 95%
