Title: New tertiary amines and their salts and processes for the preparation thereof
Filed: 1955-12-28
Abstract: The invention comprises amines of the general formula <FORM:0802724/IV (b)/1> and acid addition and quaternary salts thereof, in which R1 and R2 are hydrogen, hydroxyl, methoxy, methyl or isopropyl, but cannot both be hydrogen.  The compounds are made (1) by treating an aminoacetonitrile of the formula <FORM:0802724/IV (b)/2> with an organo-magnesium halide of the formula <FORM:0802724/IV (b)/3> wherein Hal is a halogen atom; (2) by condensing an aldehyde R1.C6H4.CHO with methylamine and treating the resulting Schiff's base with an organo-magnesium halide of the formula III to form a secondary amine which is N-methylated to give the tertiary amine I; (3) by di-N-methylating the corresponding primary amine; or (4) by treating an aldehyde R1.C6H4.CHO with dimethylamine and n-butanol to give an a -dimethylaminobenzyl butyl ether R1C6H4-CH(N(CH3)2) -O-C4H9, which is treated with the organo-magnesium halide III.  The amines prepared by these methods may be converted into salts, if desired.  Reactions with the organo-magnesium halide are suitably carried out in solution in diethyl ether, dibutyl ether, benzene or tetrahydrofuran, conveniently at or below the boiling-point of the solvent.  The N-methylation reactions are suitably effected by means of formaldehyde in an aqueous medium.  Examples describe the preparation of amines of the formula I in which R1 and R2 respectively have the values: (1) and (12)-(14) methoxy, hydrogen; (2) methyl, hydrogen; (3) hydroxy, hydrogen; (4) isopropyl, hydrogen; (5) methoxy, methyl; (6) hydroxy, methyl; (7) methyl, methyl; (8) hydrogen, methyl; and (9) hydrogen, methyl; also (10) and (11) quaternary salts of 1 - (4 - methoxyphenyl) - 1 - dimethylamino - 2 - phenyl-ethane are prepared. Intermediates.  4 - Methoxy - benzal - methylimine is made by reaction of anisaldehyde with methylamine; treatment of this with the Grignard reagent derived from benzyl chloride gives 1 - (4 - methoxyphenyl) - 1 - methylamino - 2 - phenyl - ethane.  Anisyl - (dimethylamino) - methyl-butyl ether is made by reaction of anisaldehyde, dimethylamine, n-butanol and potassium carbonate at 100 DEG  C. in a sealed tube.
