Abstract
Antihistaminic salts are prepared by reacting gentisic acid with an N-aminoalkylphenothiazine substituted in the amino group. A solvent such as alcohol is used, and double decomposition may be effected between the hydrochloride of the N-aminoalkyl-phenothiazine and the gentisic acid sodium salt. An example describes the preparation of the gentisic salt of N-diethylaminoethyl-phenothiazine.
