Yield:709-98-8 88%
Reaction Conditions:
with iron(III) chloride;chlorine in N,N-dimethyl-formamide at 70; for 3 h;Temperature;
Steps:
1
Under stirring,Adding N-(4-chlorophenyl)propanamide (0.1 mol),N,N-dimethylformamide (50 ml) and iron trichloride (0.01 mol),Slowly warm up to 70 ° C,Passing chlorine gas to react,The tail gas produced by the reaction is absorbed by 30% liquid alkali.After 3 hr, TLC detected complete reaction.Stop the reaction,Add 100 ml of deionized water to the reaction solution.Stirring,Filtered to give a white solid.Melting point 91~92°C,The yield was 88% based on N-(4-chlorophenyl)propanamide (0.1 mol).The purity of HPLC was 98.9%.The solid obtained is the enemy.
