Procedure

A solution of N-[1-(2-(ethoxycarbonyl)hydrazinocarbonyl)ethyl]-2',6'-dimethylmethanesulphonanilide (5.6 g) in ethanol (75 ml) and 10% sodium hydroxide solution (75 ml) was heated on a steam bath for 21/2 hours, and then the ethanol was evaporated off. The aqueous solution remaining was acidified with dilute hydrochloric acid, heated on a steam bath for 1 hour, and then filtered. The filtrate was just neutralised with dilute sodium hydoxide solution, saturated with sodium chloride and extracted with chloroform. The chloroform solution was dried and evaporated, and the residue gave colourless crystals of N-[1-(hydrazinocarbonyl)ethyl]-2',6'-dimethylmethanesulphonanilide from a solution in toluene/60°-80° petrol. Yield 2.6 g (58%). Melting point 115°-118°.
