Synthesis of Some Substituted Benz/Acetamidines [PDF]

open access: yesمجلة التربية والعلم, 2006
In the present work the synthesis of subtituted acetamidines was achieved. Phthalic anhydride was treated with p-aminobenzoic acid or glycine to give the corresponding acid which then converted to acid chloride with thionyl chloride.
