以6-甲基烟酸甲酯为原料合成6-甲基-3-甲醇吡啶的一般步骤:在-5℃下,向搅拌的6-甲基烟酸甲酯(21g; 140mmol; 1当量)的无水THF(150mL)溶液中缓慢滴加1M LiAlH4的THF溶液(210mL; 210mmol; 1.5当量)。滴加完毕后,将反应混合物在23℃下继续搅拌2小时。随后,将混合物冷却至-10℃,并用硫酸钠十水合物和乙酸乙酯小心淬灭反应,直至停止产生气泡。将混合物通过硅藻土垫过滤,滤液经减压浓缩至干,得到6-甲基-3-甲醇吡啶(17g,产率100%)。产物经1H NMR(DMSO-d6)表征:δ 8.37(s,1H),7.59(dd,1H,J = 2,8Hz),7.19(d,1H,J = 8Hz),5.22(t,1H,J = 6Hz),4.47(d,2H,J = 6Hz),2.45(s,3H)。
