Patent GB-836934-A (GB)
Title: Phenolic amino compounds
Inventor: BROWN JOSEPH PATRICK
Filed: 1957-10-03
Abstract: The invention comprises a process for the preparation of 2-(N,N - disubstituted - amino)-methyl-4-alkyl phenols of the structure <FORM:0836934/IV (b)/1> (in which the R's are alkyl groups or together form a chain, the ends of which are linked to the N atom, and R1 is an alkyl group of at least 4 carbon atoms), by reduction of the corresponding alkyl-salicyl-disubstituted amides of the structure <FORM:0836934/IV (b)/2> The reduction is preferably carried out by means of lithium aluminium hydride in an anhydrous system; but catalytic hydrogenation may also be employed.  In an example, a mixture of 5-n-tetradecylsalicyldimethylamide, dry ether and lithium aluminium hydride is refluxed; and then, after standing overnight, the reaction-mixture is treated with aqueous sodium hydroxide and wet ether.  Filtration and evaporation of ether from the filtrate gives 2-dimethylamino-methyl-4-n-tetradecylphenol.  This compound together with its salts, is claimed per se.  The hydrochloride is prepared by dissolving the free base in methanolic hydrogen chloride, and then allowing the solution to evaporate.  This salt has anti-tubercular properties.  It is stated that the R groups, in the above formul , can form with the N atom a piperidine or morpholine ring.  5 - n - Tetradecylsalicyldimethylamide is obtained by the action of thionyl chloride, followed by dimethylamine, on 5-n-tetradecylsalicylic acid. 5-n-Tetradecylsalicylic acid is obtained by the reduction of 5-myristoylsalicylic acid with zinc amalgam and aqueous hydrochloric acid.  5-Myristoylsalicylic acid is obtained by the reaction between salicylic acid and myristoyl chloride in the presence of aluminium chloride.

[Class 135] In a clutch controlling mechan. ism for motor vehicles, an intake valve 59 and an exhaust valve 58 for controlling the flow of pres. sure fluid to a servomotor con. nected at 27, are movable ir response both to engine speed anc to the pressure of the fluid ir the servomotor by a member 53 connected with or forming the valve seat 68 and couplec directly to a centrifugal device 29 subject to the engine speed The member 53 is secured to a diaphragm 54 subject through a choke 71 to the pressure of the fluid in the servomotor. The valves 58, 59 are of dumb-bell form, and at idling speeds a spring 70 moves the seat 68 into contact therewith, thus closing the exhaust passage through ports 69 to an exhaust pipe 28, and opening the inlet from a supply pipe .26 against the action of a spring 60; the servomotor is thus actuated to disengage the clutch. As the speed increases the centrifugal device 29 assisted by the pressure on the diaphragm 54 moves the member 53 to the left, allowing the valve 59 to shut off the fluid supply. Further movement towards the left withdraws the seat 68 from the exhaust valve 58 and the pressure in the servomotor falls ; at the same time pressure is reduced on the diaphragm 54 so that the opening of the exhaust valve is damped to allow a smooth and graduated reengagement of the clutch.
