反応手順

2,3-Dichlorothiophenol (4.94 g, 28 mmol) was placed in a flask with acrylic acid (2.11 g, 29 mmol) and stirred at 50° C. for 3 hours. The reaction mixture was poured into 10% Na2CO3 and extracted with ether. The aqueous layer was acidified with concentrated hydrochloric acid, extracted with ether, washed with brine, dried over MgSO4, and concentrated in vacuo to give the 3-(2,3-dichlorophenylthio)propanoic acid (3.88 g), contaminated with some acrylic acid, as a clear oil which was used without further purification in the next step.
