Thionyl Chloride → HCID 57968127, compound

Participants

Reaction Steps

4-{[6-(acryloyloxy)hexyl]oxy}benzoic acid (4) (2.8 g (grams)) was dissolved in tetrahydrofurane (THF, 100 ml (milliliters)) at a room temperature, and a temperature of the resulting mixture was adjusted to a temperature of 0° C. (Celsius). Then, thionyl chloride (12 ml (milliliters), 1M in THF) was added to the mixture, and stirred for 30 minutes. Then, 4-(6-bromohexyloxy)phenol (2.5 g (grams)) and triethyl amine (13 ml (milliliters)) were added to the resulting reaction mixture, stirred at 0° C. (Celsius) for 1 hour, and then stirred at a room temperature overnight. Next day, a saturated ammonium chloride aqueous solution was poured into the reaction mixture, and the reaction was completed. The resulting reaction mixture was extracted three times with ethyl acetate (50 ml (milliliters)), and waster was removed over magnesium sulfate. Then, the solvents were evaporated, and the resulting reaction mixture was then purified using a column chromatography (developer solution: ethylacetate/hexane=1/2 volume ratio) to obtain 4-(6-bromo hexyloxy)phenyl 4-{[6-(acryloyloxy)hexyl]oxy}benzoate (5) (3 g (grams)).
