Reaction Conditions:
Stage #1:propylamine;1-(2-(oxiran-2-ylmethoxy)phenyl)-3-phenylpropan-1-one at 20 - 50; for 6 h;
Stage #2: with hydrogenchloride for 1 h;Reflux;
Steps:
5 Example 5
In the reactor, add 248g of 2'-hydroxydihydrochalcone sodium salt,Epichlorohydrin 1L,Heated at 110 for 8 hours,After the reaction is complete,The excess epichlorohydrin was distilled off under reduced pressure, and the residue was cooled to room temperature,Add 600g of n-propylamine and heat to 50 for 6 hours,After the reaction is completed, the excess n-propylamine is distilled off under reduced pressure,Add 1.5L of 10% hydrochloric acid to the remainder and heat to reflux for 1 hour to cool down and crystallize,Filter, filter cake recrystallized with 95% ethanol,Finally getThe target product, propafenone hydrochloride 281g, yield 74.5%.
