c The same compound was also obtained from methyl 4-arsonosophenoxyacetate and ethanolamine, yield 92%. methylol group was formed on the amide nitrogen and one on the arylamino nitrogen in the last two instances. The position of the methylol group on nitrogen rather than on the benzene ring was proved by hydrolysis to 4-arsonophenoxyacetic acid and N-4-arsonophenylglycine.4-Aminobenzenearsonous acid reacted with sodium formaldehyde bisulfite to yield a sulfomethyl derivative. 4-Cyano-and 4-hydrazinobenzenearsonous acid9•10 were obtained by reduction of the corresponding arsonic acids.
