Definitions
- This invention relates to the manufacture oi basic esters of polyarylacetic acids, which are compounds of considerably greater compatibility than the said ester of benzilic acid.
- the easily accessible dialkylaminoethanol ester of diphenylacetic acid has an extraordinarily powerful effect on the unstriated mus- 2g cles. . This is unexpected, since hitherto it has been supposed that the presence of an aliphatic hydroxyl group in the acid residue (tropic acid, atrolaotic acid, atroglyceric acid, mandelic acid or benzilic acid) favored the action.
- the new compounds may be made by acting upon polyarylacetic acids or on a halide, ester or anhydride thereof, in the presence or absence of a condensing agent, with an aminoalkanol disub stituted at the nitrogen atom, or by the action of a reactive ester of an aminoalkanol, disubstituted at the nitrogen, on a polyarylacetic acid or a salt thereof, if desired in the presence of an agent which binds acid.
- polyarylacetic acids may be converted into their halogen- 36 alkanol esters and the latter caused to react with a secondary amine.
- alkylene-halogen-hydrines 40 are caused to react on polyarylacetic acids or the halides, esters or anhydrides thereof, in the presence or absence of condensing agents, or that.
- hydroxyl-group which may be present by halogen.
- an alkyl halide an alkylene halide, an aryl sulfonic acid ester, a. dialkylsulfate, 0 an arylalkyl halide or the like, quaternary ammonium compounds of the bases in question can be produced.
- esters of aminoalkanols are particularly included esters of these with hydrohalogen acids or arylsulfonic acids or the like.
- the new compounds are useful for therapeutic application.
- 10.6 are of a,a-diphenylacetic acid are treated with thionyl' chloride and the diphenylacetyl chloride thusproduced is caused to react with 5 ⁇ parts of diethylaminoethanol at C.
- the unadiphenylacetic acid 2 (diethylamino) -ethauolesterhydrochloride of the formula CaHu V /CSEB err-comom-cm-u thus produced is recrystallized from ethyl ace-
- Example 2 42.4 parts of diphenylacetic acid, 41 parts of chlorethyl-diethylamine-hydrochloride, 55 parts of potassium carbonate and 120 parts of acetone are together heated to boiling in a reflux apparatus until the reaction is complete.
- the same compound may also be obtained by causing equivalent quantities of diphenylacetic acid ethylmethylor another ester to react with diethylaminoethanol in the heat, and'fractionating the reaction product in a vacuum.
- Example 3 11.5 parts of'diphenylacetic acid chloride-are caused to react, in presence ot- 30 parts of dry'pyridine, with 6.5 parts of allylethvlaminoethanol of the formula (boiling at 172 C. at 740mm. pressure, obtained from allylbromide' and ethylaminoethanol) The product of the reaction is extracted with ether ethanol; the reaction mass is extracted with ether,
- Example 5 23 parts of diphenylacetic acidchlorlde .are caused toreact with 8 parts of ethylenechlorohydrine in presence of pyridine. The reaction product is shaken with ether and water; the ethereal solution is dried, the solvent evaporated and the residue fractionated in a vacuum. The
- ethylene chlorhydrine - also other ethylene halogen-hydrines, for example ethylenebromohydrinamay be used.
- an alkali salt of the diphenylacetic acid is caused to react with an ethylenedihalide as, for instance, ethylene chlorobromide, ethylene bromide or ethylene iodide, or an ethylene halogen-hydrine is caused to react thereupon, and the hydroxyethanol ester thus obtained is treated, for instance, with thlonyl chloride.
- diphenylacetic acid-2-methylethylaminoethanol'ester (a colorless oil of boiling point 136-138? C. at 0.015 mm. pressure) diphenylacetic acid- 2 di-n-butylaminoethanol ester (boiling point 163-l65 C. at 0.01 mm. pressure, sulfate melting point 139-140 C.) diphenylacetic acid-2- point 149-151 C.), diphenylacetic acid-meta-dimethyl aminocyclohexanol ester (viscous oils of boiling point PTO-180 C. at 0.035 mm. pressure); the orthoand para-compounds are also forming viscous oils.
- the parent materials hitherto not known for the production of the above compounds are ob tained as follows: methylethylaminoethanol (boiling point 146-148 C. at 734 mm. pressure) from ethylaminoethanol and formaldehyde in presence of formic acid; m-dimethyl aminocyclohexanol (boiling point 101-104 C. at 6 mm. pressure) by methylating m-aminocyclohexanol of melting point 73 C., the latter being obtained by reducing m-acetylaminophenol with a catalyst and by subsequent saponification.
- the orthoor para-compounds are obtained in an analogous manner.
- a process for the manufacture of basic W esters which comprises causing products of the formula ⁇ C-CO can formulo wherein R represents a member of the group consisting' of hydrogen and phenyl and a: represents a member of the group consisting of oxyalkyl and halogen, toreact with products of the formula HO-CHPCM wherein 11 represents a. member of the group consisting of a dialkylamine, an alkyl-allylaniine and a. piperidine ring.
