Dimethylamine → 2-Dimethylaminomethyl-6-methylpyridine

참여 물질

반응 단계

2-bromomethyl-6-methylpyridine is treated with dimethylamine to give the corresponding tertiary amine, 2-dimethylaminomethyl-6-methylpyridine. The tertiary amine is treated with cyanomethyl benzenesulfonate, as in Preparation II, to give dimethylcyanomethyl-(6-methyl-2-picolyl) ammonium benzene sulfonate. The quaternary ammonium salt is rearranged using sodium hydride and alkylated with benzylbromide according to the procedure described in Example 2. The alkylated cyanoamine is decyanated with sodium borohydride in ethanol to give the desired product which can be purified through its picrate.
