     BACKGROUND OF THE INVENTION 
     FIELD OF THE INVENTION 
     The present invention relates to a piperidine derivative and hypotensives containing the same. 
     DESCRIPTION OF THE BACKGROUND 
     It is said that there are about 13,000,000 patients with hypertension in Japan and its frequency of occurrence in individuals becomes greater with advancing age. Further, as the age of a given population increases, increased attention is directed to hypertension which becomes more and more of a dangerous factor in severe heart and cerebral diseases represented by cardiac infarction and cerebral apoplexy. In recent years, calcium antagonists or angiotensin convertase inhibitors have been widely used as excellent primary selection drugs for treatment of hypertension. But the pharmaceutical effects or safety of these hypotensives have recently come into question. 
     A need therefore continues to exist for new hypotensive agents which exhibit excellent pharmaceutical effects and safety which can be industrially prepared at low cost and in a simple manner. 
     SUMMARY OF THE INVENTION 
     Accordingly, one object of the present invention is to provide an effective hypotensive agent which is relatively simple to prepare at low cost. 
     Briefly, this object and other objects of the present invention as hereinafter will become more readily apparent can be attained by a piperidine derivative of formula (I): ##STR2## wherein A is a fused aromatic ring; R is hydrogen, chloro or methoxy; X is (CH 2 ) n , which may be substituted, in which n is 0 or an integer of 1 to 10, --CH═CH--, --C═C--, --O--, --S--, --NH--, --N(COCH 3 )--, --N(COOC 2  H 5 )--, --N(CHO)--, --N(CH 3 )--, --CO--, --SO--, or --SO 2  --; Y is --CH═CH--, --CH 2  CH 2  --, --CH 2  CO--, --O--, --S--, --NH--, --OCH 2  --, --SCH 2  --, --NHCH 2  --, --CH(OH)CH 2  --or --CH (OH) CH (OH) --; and Q is substituted or unsubstituted n-hexyl, carboxypropyl, ethoxycarbonylpropyl, cyanopropyl, cyclohexyl, phenyl, indanyl, naphthyl, tetrahydronaphthyl, benzocycloheptyl, piperidinyl, tetrahydroisoquinolinyl, indolyl, pyrolyl, furyl, thienyl, thiazolyl, oxazolyl or N-methylpyrolyl, wherein any one or more of the --(CH 2 )-groups of the hexyl, carboxypropyl, ethoxycarbonylpropyl and cyanopropyl groups may be replaced by --CH═CH--, -- C═C--, --O--, --S--, --NH--, --N (COCH 3 ), --N(COC 2  H 5 )--, --N(CHO)--, --N(CH 3 )--, --CO--, --SO-- or --SO 2  --, and wherein one or more of the --(CH 2 )-groups in X and Q may be substituted by --(CH 2 ) 4  -- or --(CH 2 ) 5  -- thereby forming a ring structure. 
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     It has now been discovered that piperidine derivatives of the formula (I) above are effective as hypotensive agents. The present piperidine derivative exhibits excellent hypotensive action, its method of synthesis is simple and its derivatives can be easily prepared. 
     In formula (I), the fused aromatic ring (A) is a fused benzene, thiophene, pyridine or the like ring. Further, in formula (I) above, substituents X and Q may be substituted by at least one substituent selected from the group consisting of H(CH2)n, wherein n is 1 to 10, C 1  (CH 2 ) 3 , allyl, phenyl, isopropyl, hydroxy, methoxy, ethoxy, fluoro, chloro, acetoxy, 2-methoxyacetoxy, ethoxycarboxy, carboxyl, methoxycarbonyl, ethoxycarbonyl, cyano, imidazolylmethyl, trifluoromethyl, benzoyl, 2-hydroxybenzyl, nitro, amino, acetylamino, propanoylamino, butanoylamino, pivaloylamino, trifluoromethylamino, methoxycarbonylamino, ethoxycarbonylamino, cinnamoylamino, methanesulfonylamino, N,N-bis(methanesulfonyl)amino, aminocarbonyl, aminosulfonyl, hydroxymethyl and acetoxymethyl. 
     The method of administration of the present piperidine derivative when used as a hypotensive, include oral and parenteral routes. Dose is determined depending upon age, body weight and condition of the patient and route of administration. Daily dose is generally 0.01 to 2000 mg/kg for oral administration. In the case of parenteral administration, the daily dose is 0.01 to 1000 mg/kg. The present piperidine derivative may be prepared in the form of ordinary preparations such as for example, tablets, powders, capsules, solutions, sugar--coated tablets or depots, which may be prepared in a conventional manner using conventional preparation aids. For example, tablets can be obtained by mixing the piperidine derivative of the present invention diluents (e.g., lactose, calcium carbonate or calcium phosphate), binders (e.g., gum arabic, corn starch or gelatin), swelling agents (e.g., alginic acid, corn starch or pregelinated starch), sweeteners (e.g., sucrose or saccharin), flavors (e.g., peppermint, Gaultheria adenothrix oil or cherry), lubricating and wetting agents (e.g., magnesium stearate, talc or carboxymethyl cellulose). 
     Having now generally described this invention, a further understanding can be obtained by reference to certain specific examples which are provided herein for purposes of illustration only and are not intended to be limited unless otherwise specified. 
     Unless otherwise indicated, the developing conditions for silica gel TLC procedures were under chloroform/methanol=9/1. Mass spectra (MS) were performed in the FD mode (m/z) and nuclear magnetic resonance spectra (NMR) were measured using tetramethylsilane as the internal standard and CDCl 3  as the solvent.

     4-(5H-Dibenzo[a,d]cyclohepten-5-ylidene)-1-hexylpiperidine hydrochloride 
     A solution of 273 mg (1 mmol) of 4-(5H-dibenzo[a,d]cyclohepten-5-ylidene)-1-hexylpiperidine, 165 mg (1 mmol) of 1-bromohexane, 745 mg (5 mmols) of sodium iodide and 414 mg (3 mmols) of potassium carbonate in 20 ml of methyl isobutyl ketone was stirred and refluxed at 120° C. overnight on an oil bath. After the reaction, the mixture was washed by adding 20 ml of water thereto. Then the organic phase was separated and the solvent was distilled off under reduced pressure. After purifying by silica gel column chromatography (eluent: methanol/chloroform, 1/100-1/50), the product was converted into the hydrochloride with an equimolar hydrogen chloride/dioxane solution.

     EXAMPLE 154 
     As test animals, four male spontaneously hypertensive rats (weight 400 to 440 g) that were sufficiently adapted for feeding and in which hypertension was confirmed were used. 
     Physiological saline aqueous solution containing 2.5% Nicolle and 2.5% ethanol of sample was intravenously administered by bolus injection at a dose of 1 ml per 1 kg of body weight. Systolic blood pressure after administration was measured by the indirect (tail-cuff) method. 
     The results are shown below.
