N,N-diethyl-p-phenylenediamine (H2NC6H4N(CH2CH3)2, MW 164.25, 40 g, 244 mmol) was dissolved in diethyl ether (200 cm3). Hydrochloric acid (40 cm3, 37%) was added. The resulting solution was concentrated by rotary evaporation to give N,N-diethyl-p-phenylenediamine dihydrochloride as a light brown solid (57.76 g, 100%). dH (250 MHz; D2O): 7.68 (2H, m, ArH), 3.45 (4H, q, 7.25, NCH2), 1.19 (6H, t, 7.25, CH3).
