The yield amounts to Preparation of triphenyl 4-fluoroxy methyl) phosphonium chloride In 300 ml benzene, 42 g of chloromethylated ether (0,26 mol) and 81 g of triphenyl phosphine are introduced and the whole mixture is heated to reflux for a night. Afer evaporation of benzene, the salt of phosphonium is allowed to crystallyse from ether. 62 g of salt of phosphonium are recovered, melting at 248 0 C. The yield amounts to 57%.
Step A l-(3-methoxy 4-benzyloxy phenyl) 2-4-fluorophenoxy) ethene Je 0. 12,2 g (0,029 mol) (4-fluorophenoxy methyl) triphenyl phosphonium chloride are dissolved in 100 ml tetrahydrofuran and the solution is cooled to 78 0 C under atmospher of argon.
To this, 16 ml of a 1,6 M (i.e 0,026 mol) solution of butyl lithium in hexane are added dropwise. After 1 hour standing at this temperature, 5 g (0,02 mol) of 3-methoxy 4-benzyloxy benzaldehyde are added then the mixture is allowed to revert G* to room temperature in two hours. The mixture is then poured on ice, made acidic at pH 4 and extracted with ether. After evaporation of the solvent, the residue is filtered on silica and 6,2 g of the phenoxy ethene are recovered.

The arterial systolic pressure has be measured by the sphygomanometric process using an electrospohygmograph NARCO (biosystems) type PE 300. The determinations of the blood pressure have been performed 24 hours after the administration of a compound of formula I to be tested. The arterial systolic pressure is calculated from the average of 6 to 8 measurements.
The obtained results are gathered in Table II It thus appears that the kinetic of the anti-hypertensive action is dissociated from that of the diuretic effect.

Compound of ex 1 is less active on the opening of potassium channels.
On the other part, in contrast of Cromakalim and Pinacidil, the opening effect on the potassium channels of the compound of ex.l is *not antagonized by GLIBENCLAMIDE. The same compound in contrast with those agents acting on the opening of the potassium channels -is glibenclamido-resistent- Its mechanism of action is not bound to the test ATP-dependent potassium channel.

F MEASUREMENT OF THE VASOCONSTRICTION INDUCED BY POTASSIUM CHLORIDE
C
be* a) Method A vasoconstriction is caused in male rats of Wistar strain, weighing 200to 350 g by increasing doses of potassium chloride ranging from to 60 mM.
37 The rats are thereafter beheaded at the thoracic aorta and the diameter of the vessels is measured.
Curves 1 and 2 gather the obtained results compound of example 1 as the piperazine disalt shows an antagonist ee merely on the contraction induced by the weakest eessI of potassium chloride (ClK at 20 mM).
The mean inhibitory dosis (IC n) has been calculated at 22 pM. The 50 cxoz e contraction induced by the highest doesisof potassim chloride (60 mM) dosa
K
is antagonized only by a strong desi of the compound of example
(IC
5 0 1,12 mM) It thus appears that it exists a dissociation of the vaso-relaxing effect of the ccmpound of example 1 after vaso-constriction by potassium chloride depending on the utilized concentration as it has been previously shown only with the potassium agonists. In contrast thereof the calcium inhibitors induce a decontracting effect at both concentrations of the vaso-constricting agent to be administered.
