2 Compounds Derived from Substituted Aminoacetic Acids 

Also obtained by action of potassium N-methyl-p-toluene sulfonamide with m-acetoxy-a-bromoacetophenone in acetone during some hours. Then, the resulting intermediate compound (m.p. 120-121°) was treated with boding 55% aqueous hydriodic acid for 1 h [4753 755]. 

Also obtained by reaction of methylamine with a-bromo-m-baizoyloxyacetophenone in isopropanol, and subsequent treatment with aqueous hydrochloric acid [4756]. Also obtained by reaction of methylamine with a-bromo-m-hydroxyacetophenone in dilute ethanol [4757,4758]. 

Preparation by reductive condensation of 3,4-dihydroxyphenylglyoxal with methylamine in ethanol under hydrogen atmosphere in the presence of 14% Pd/C [4752]. 

Also obtained by degradation of p-toluenesulfonamide, prepared from 3,4-dime-thoxy-a-methyl-aminoacetophenone, with refluxing 37% hydrochloric acid (150-160°) for 2 h under carbon dioxide [4739].
