Patent GB-823197-A (GB)
Title: N-substituted-piperidinecarboxylic acid amides and process for their preparation
Filed: 1958-01-20
Abstract: The invention comprises compounds of the general formula <FORM:0823197/IV (a)/1> (wherein n is 1-3 and B represents a morpholino, 2 : 6-dimethylmorpholino, piperidino, pipecolino or pyrrolidino group) and their nontoxic acid addition salts, and the preparation thereof by catalytic hydrogenation of a quaternary compound of the formula <FORM:0823197/IV (a)/2> (wherein X#q represents a halide ion).  The hydrogenation may be effected under increased temperature and pressure (e.g. 50 DEG  C. and 60 lbs./sq. inch) in the presence of platinum oxide, advantageously in water. The products are useful as hypotensive agents.  In examples: (1) picolinic acid is reacted with ethyl chloroformate in methylene chloride in the presence of triethylamine, the product is reacted with morpholine, and the resulting 2-morpholinocarbonylpyridine is refluxed with b -phenethylethyl bromide in acetonitrile to form 2-morpholinocarbonyl - 1 - b  - phenethylpyridinium bromide, which is hydrogenated to 2-morpholinocarbonyl-1-b -phenethypiperidine hydrobromide and the base liberated with caustic soda; (2) a -pipecoline in place of morpholine yields 2-a -pipecolinocarbonyl - 1 - b  - phenylethylpiperidine; (3) nicotinic acid is refluxed with morpholine in xylene and the resulting 4-nicotinoylmorpholine is treated as in (1), producing finally 3 - morpholinocarbonyl - 1 - b - phenethylpiperidine; (4) piperidine in place of morpholine yields 3 - piperidinocarbonyl - 1 - b  - phenethylpiperidine; (5) the b -phenethyl bromide in (3) is replaced by benzyl chloride, producing finally 3 - morpholinocarbonyl - 1 - benzylpiperidine, and (6) by 3-bromopropylbenzene to give 3-morpholinocarbonyl - 1 - g  - phenylpropylpiperidine; (7) isonicotinic acid is reacted as in (1) to form finally 4 - morpholinocarbonyl - 1 - b  - phenethylpiperidine; (8) g -pipecoline in place of morpholine in (1) gives 2-g -pipecolinocarbonyl - 1 - b  - phenethylpiperidine; (9) pyrrolidine and nicotinic acid in place of morpholine and picolinic acid in (1) yield 3-pyrrolidinocarbonyl - 1 - b  - phenethypiperidine; (10) and (11) replacement of nicotinic acid in (9) by isonicotinic acid or 2-pyridinecarboxylic acid produces 4- or 2-pyrrolidinocarbonyl-1-b -phenethylpiperidine; (12) 2 : 6-dimethylmorpholine in place of morpholine in (7) gives 4-(2 : 6-dimethylmorpholino) - carbonyl - 1 - b  - phenethylpiperidine.  Salt-forming acids specified in addition to hydrogen halides are sulphuric, nitric, phosphoric, sulphamic, tartaric, glycollic, citric, maleic, succinic, acetic, benzoic, cinnamic, malic and ascorbic.

Initially, the regulators P1, P2 are gradually compressed and P3 is left uncompressed; when P1, P2 are fully compressed P3 is compressed to connect the batteries 1, 2 in series, the current through P1, P2 being finally blocked by rectifiers R1, 1R2. Regulators P1, P2 may be replaced by a single regulator P1/2. There may be two motors M1, M2, Fig. 3, controlled by further carbon-file regulators P4, P5 and a rectifier R3. Initially, regulators P4, P5 are uncompressed so that the motors are in series across the supply, these regulators being gradually compressed to connect the motors in parallel. Thus in conjunction with the circuit of Fig. 1, the circuit of Fig. 3 permits the voltage across each motor to gradually increase from zero to “, from “ to ¢ and from ¢ to the total voltage of the batteries 1, 2. In a further modification, Fig. 5, employing regenerative or rheostatic braking, F represents the series field winding of the motor having armature A, the braking being controlled by a carbon-pile regulator P6.
