Procedure

A portion of the paste (693 parts) from (a) was added at 60°-90° C. to a mixture of 232.5 parts of water and 270 parts of concentrated hydrochloric acid, heated to 95° C. and held at this temperature for 1 hour. Addition of 700 parts of ice cooled the solution to 20° C. Upon stirring or standing for 24 hours crystals of N-(3'-amino-4'-methoxyphenylsulfonyl)-N-methylaminomethylphosphonic acid formed which melted at 218°-220° C. The hydrolysis solution, after cooling with ice, was used directly for synthesis of dyes; isolation of the product was not necessary.
