N-[(Imidazolin-2-yl)amino]indolines and N-[(imidazolin-2-yl)amino]-1,2,3,4-tetrahydroquinolines, previously described in patent literature as hypertensive agents, were synthesized and tested in vitro for their affinities to α1- and α2-adrenoceptors as well as imidazoline I1 and I2 receptors. The compounds most potent at either α1- or α2-adrenoceptors were administered intravenously to normotensive Wistar rats to determine their effects on mean arterial blood pressure and heart rate. Upon intravenous administration at dose of 0.1 mg/kg to normotensive male Wistar rats, the initial transient pressor effect was followed by long-lasting hypotension and bradycardia. In view of the above results the 1-[(imidazolin-2-yl)amino]indolines and [(imidazolin-2-yl)amino]-1,2,3,4-tetrahydroquinolines are now found to possess circulatory profile characteristic of the centrally acting clonidine-like hypotensive imidazolines.

The present invention relates to a process for the preparation of high-grade chloramine by the action of commercial eau de Javelle of 100 chlorometric degrees on a solution of ammonia in the presence of ammonium chloride. According to this process, the chloramine is obtained having a content greater than or equal to 2 mol L?1, that is to say, greater than or equal to 10.3%. The process can be carried out continuously or discontinuously.
