A solution of 10.5 gm (0.03 mol) of diamine 15, 4.0 gm (0.03 mol) of benzyl chloride, and 15 gm of MeOH were charged to the flask and heated to reflux. After 1.5 hours, GC showed 5-10% benzyl present along with amine. The reaction was allowed to reflux overnight (ca. 15 hr). GC showed the benzyl chloride consumed and some amine still present. Benzyl methyl ether was formed as a by-product of the reaction. Excess amine and other residue was removed by vigorous washing of the crude product in ether. After rotary evaporation, 10 gm (70% crude yield) of Quat 5 was obtained.
