Patent GB-751522-A (GB)
Title: Novel derivatives of úÝ-hydroxy-aniline and the manufacture thereof
IPC: C07C233/16
Filed: 1954-03-16
Abstract: The invention comprises compounds of the formula <FORM:0751522/IV(a)/1> wherein R stands for an alkyl or alkenyl group containing from one to six carbon atoms or an aralkyl group, R1 and R2 may each be a hydrogen atom or an acyclic hydrocarbon radical, R3 and R4 are acyclic hydrocarbon radicals or may be combined so as to form with the N-atom to which they are attached a heterocyclic radical, X-stands for an anion of a strong acid and Y stands for an optional substituent which, if present, is an electronegative substituent.  Such compounds are obtained by quaternizing a tertiary amine of the formula <FORM:0751522/IV(a)/2> with a benzyl or p-substituted-benzyl quaternizing agent (the p-substituent being an electronegative group) and, if desired, exchanging the anion of the quaternary salt so formed for another anion by passing the salt through an anion-exchange resin.  As quaternizing agents an ester of benzyl alcohol or p-substituted benzyl alcohol with hydrochloric, hydrobromic, hydriodic, benzene sulphonic or p-toluenesulphonic acid may be used. Para-substituents mentioned are chloro, nitro, acetyl and methylsulphonyl substituents.  The products are antihelmintic and antiprotozoal agents.  In Example (1) (m-allyloxyphenylcarbamylmethyl)-diethyl - (p - nitrobenzyl) - ammonium bromide is prepared by reacting m - allyloxyphenylcarbamylmethyl diethylamine with p-nitrobenzyl bromide. Further examples illustrate the preparation of compounds of the first formula above wherein R is selected from methyl, ethyl, allyl, isopropyl, propyl, butyl and benzyl radicals, R1 and R2 are selected from hydrogen and methyl, R3 and R4 separately (or together, in appropriate cases, with N), are selected from methyl, ethyl, propyl, morpholino and piperidino radicals, and the benzyl radical has in some case in the p-position nitro, chloro or acetyl substituents. Example 25 includes also the conversion of a quaternary ammonium bromide to the corresponding chloride by passage over an anion-exchange resin.  Other groups mentioned are for R: vinyl and butenyl radicals and for R3 and R4: butyl and amyl radicals.  The tertiary amine starting are obtained by reacting the appropriate m-amino phenyl ether with an a -halogeno-acid halide or anhydride and condensing the substituted anilide with a secondary amine. m-Allyloxyphenyllcarbamylmethyl diethylamine is obtained by reducing m-allyloxynitrobenzene (from the reaction of m-nitrophenyl with allyl bromide), reacting the m-allyloxyaniline obtained with bromo-acetyl bromide and condensing the a -bromo-m-allyloxy acetanilide obtained with diethylamine.  By similar reactions are obtained a -chloro-m-allyloxy acetanilide which is reacted with dipropylamine to give (m-allyloxy-phenyl carbamylmethyl)-dipropylamine, and similar compounds of the second formula above where R, R1, R2, R3 and R4 are selected from the groups previously referred to.

As shown in Fig. 2, the valve arrangement comprises a spool 68 spring- biased to a central position in a bore 46. With conduit 116 acting as the delivery conduit, pressure therein acts on the left-hand end of spool 68 forcing it to the right to uncover inlet port 58 to the motor 32, and to connect outlet port 62 to the return conduit 118 by a groove 72 on the spool 68. The parts are connected to the motor through tubes 86, 100 in oversize bores 64, 66 and formed with radial bores 88, 102. On overrunning of motor 32 occurring, due to an unbalanced load, the delivery pressure 116 falls and spool 68 moves back towards the left to throttle the exhaust. With line 118 acting as the delivery line, the spool acts in an equivalent fashion in the opposite direction. Grooves 74 are provided on the spool to equalize the external pressures acting thereon.
