2,3-EPOXYPROPYL-4-METHOXYPHENYL ETHER synthesis

4synthesis methods
-

Yield: 97.3%

Reaction Conditions:

Stage #1:4-methoxy-phenol with potassium carbonate in acetone at 20; for 0.5 h;
Stage #2:epichlorohydrin in acetone at 60 - 65; for 72 h;

Steps:

1.A [Example 1] Synthesis of Diacylglycerol Lactone Compound (EC-A129)
A. As shown in Reaction 1a below, 50 g (402.77 mmole) of 4-methoxyphenol was dissolved in 1500 ml of acetone. Then, 278 g (2013.8 mmole) of K2CO3 was added and stirred at room temperature for 30 minutes. 126 ml (1611.1 mmole) of epichlorohydrin was added to the 4-methoxyphenol solution, the temperature was raised to 60 to 65° C., and refluxed for 72 hours. The reaction was confirmed by TLC (ethylacetate(EA):hexane(Hex)=1:9). When the reaction was completed, the reaction solution was filtered by a celite filter, the filtrate was concentrated. The concentrate was purified with a flash column (eluent:ethyl acetate(EA):hexane(Hex)=1:10 (volume ratio) mixture) to obtain 68 g of the target compound (yield: 97.3%)
