Ethyl magnesium bromide was reacted with 4-phenylbutylnitrile to provide ethyl 3-phenylpropyl ketone. The ketone was reacted with formamide and formic acid to afford 1-ethyl-4-phenylbutylamine. Methylation of the amine by reaction with formaldehyde and formic acid provided N,N-dimethyl-1-ethyl-4-phenylbutylamine. Quaternization of 6.2 g. of the dimethylamine according to the procedure of Example 62 afforded 6.56 g. of N,N,N-Trimethyl-1-ethyl-4-phenylbutylammonium bromide. M.P. 183°-185° C.
