2-Iodobenzoic acid → 2-[(2-Methoxyphenyl)sulfanyl]benzoic acid

Participants

Reaction Steps

Stir under reflux for 3 hours a mixture of 70 g (0.5 mole) of o-methoxythiophenol, 120.5 g (0.486 mole) of o-iodobenzoic acid 81.7 g (1.46 mole) of potassium hydroxide, 85 g (1.34 mole) of copper powder and 800 ml of water. Filter the reaction mixture hot and again filter the filtrate through celite. Acidify the filtrate with concentrated hydrochloric acid. Separate the precipitate, wash well with water and dry in vacuo at 70° C. to obtain the title product. (m.p. 198°-200° C.).
