Alkylation of 4-acetamidophenol with various alkyl halides gave alkylated derivatives 1a-d which were further reduced to form amines, 2a-d. A separate reaction of phosphonitrilic chloride trimer and methyl-4-hydroxybenzoate yielded 3, hexa-(oxy-4-methyl benzoate) cyclotriphosphazene which was then r...
