Ethyl bromoacetate → Ethyl 2-[(4-hydroxyphenyl)sulfanyl]acetate

関与物質

反応手順

Ethyl bromoacetate (21.5 mL, 194 mmol) and potassium carbonate (50.7 g, 367 mmol) were added to a DMF (450 mL) solution of 4-mercaptophenol (23.1 g, 183 mmol), and the mixture was stirred at room temperature overnight. The solvents were distilled off under a reduced pressure, water was added to the residue, and the product was extracted with ethyl acetate. The organic layer was washed with a saturated sodium chloride solution, and then dried over anhydrous sodium sulfate, and solvents were distilled off under a reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=5:1), to give 30.3 g (78%) of the captioned compound.
