Abstract
544,836. Sulphonamido compounds. BOOTS PURE DRUG CO., Ltd., LEVENE, H. H. L., and PYMAN, F. L. March 21,1941, No. 3896. [Class 2 (iii)] p-Sulphonamido-benzamidine and its derivatives substituted in the amino group are prepared by re-acting #-cyanobenzene-sulphonamide'first with alcoholic hydrochloric acid and then with an alcoholic solution of ammonia or of an amine such as methylamine. The products possess therapeutic properties, and in the form of their salts dissolve in water to a neutral solution. An example is given of the preparation of p-sulphonamido-benzamidine hydrochloride..
