Abstract
|
|
|
|
2-Ethoxy-4-acetamidobenzoate(III) was synthesized by ethylation of N-formyl compound obtained with formulation of methyl 4-aminosalicylate and 2-ethoxy-4-acetamidobenzamide (VIII) was synthesized by ethylation of 4-acetamidosalicylamide (VII) formed by reacting methyl 4-acetamido-2-acetoxy benzoate with concentrated ammonia water under pressure. 2-Ethoxy-4-acetamido benzamide (VIII) was also synthesized by acetylation of 2-ethoxy-4-aminobenzamide (VI) obtained by pressure reaction of methyl 2-ethoxy-4-formylamidobenzoate (I) with concentrated ammonia water.
