Triethylamine → HCID 13066646, compound

Participants

Reaction Steps

In 80 ml of tetrahydrofuran were dissolved 2 g of methyl 2-(2'-acetoxybenzamido)-4-aminobenzoate and 11.8 g of 2-acetoxybenzoylchloride, and to the solution was added dropwise a solution of 0.6 g of triethylamine in 5 ml of tetrahydrofuran while stirring under cooling with ice. Ten minutes after completion of the addition, the mixture was returned to room temperature, followed by stirring at that temperature for one hour. The reaction mixture was then poured into diluted hydrochloric acid-ice to precipitate crystals. The crystals were recovered by filtration and recrystallized from methanol to obtain 2.0 g of methyl 2,4-bis(2'-acetoxybenzamido)-benzoate having a melting point between 143° - 145°C. This product was confirmed to be identical to that obtained in Example 6.
