Pyridine → 4-[3-(1-Adamantyl)-4-methoxybenzoylthio]benzoic acid

Participants

Reaction Steps

In a round bottom flask, there are introduced 1.7 g (11 mmoles) of 4-mercaptobenzoic acid and 20 ml of pyridine. There is then slowly added a solution of 3.4 g (11.17 mmoles) of 3-(1-adamantyl)-4-methoxybenzoic acid chloride in 50 ml of dichloromethane. The reaction mixture is stirred at ambient temperature for 8 hours, evaporated to dryness, taken up in 100 ml of water and acidified to pH 5 with 1N HCl. The solid is filtered, washed with water and dried at 60° C. under a vacuum, then recrystallized in dioxan. 3.3 g (75% yield) of 4-[3-(1-adamantyl)-4-methoxybenzoylthio]benzoic acid having a melting point of 264° C. are obtained.
