| titleOfInvention | New quaternary amino ethers |
| abstract | The invention comprises quaternary amino-ethers of the general formula <FORM:0781407/IV (a)/1> wherein X represents a halogen atom, and the preparation thereof by reacting at an elevated temperature an amino-alkoxide of the general formula <FORM:0781407/IV (a)/2> with a diethylaminoethyl halide of the general formula <FORM:0781407/IV (a)/3> wherein M represents an alkali metal and Y represents a halogen atom, and the tertiary amino-ether thus obtained is reacted with approximately two molecular proportions of a methyl halide. The reaction with the amino-alkoxide may be carried out at a temperature within the range of 150 DEG to 250 DEG C. The reaction with the methyl halide is preferably carried out in an inert organic solvent, e.g. methanol. In an example, the sodium salt of b -pyrrolidino-ethanol is reacted with diethylaminoethyl chloride to form the b -(N-pyrrolidinyl)-ethyl b 1-diethylaminoethyl ether which is then reacted with methyl iodide to form the diodide of N-diethylmethylammonium-ethoxyethyl - N1 - methylpyrrolidine of the above general formula wherein X represents iodine. |
