To a stirred solution of 3,4-dinitrotoluene (3.64 g, 20 mmol) and N,N-dimethylethylenediamine (1.76 g, 20 mmol) was heated at 80° C. in dimethyl sulfoxide and catalytic amount of TDA-1 for 2 hours. N,N-Dimethyl-2-(5-methyl-2-nitroanilino)ethanamine was isolated in 80% yield (3.6 g, 16 mmol) after aqueous work-up. Quaternization was achieved in quantitative yield with methyl iodide and dimethylformamide. Its melting point was 225°-7° C.
