2-氨基吡啶制备

通常是在溶剂存在下，由氨基钠与吡啶反应。反应时逸出氢气，同时生成氨基吡啶的钠衍生物，后者经水解即生成游离的氨基吡啶。操作示例1将氨基钠加入干燥的甲苯中，加热回流，加吡啶同时通入氮气，继续回流6h。反应结束，冷却至20℃，通氮，缓缓加水，加毕，升温至60-70℃，静置分取甲苯层，水层保持60-70℃，用甲苯提取2次，减压回收甲苯，收集100-140℃（8kPa）馏出液，得2-氨基吡啶。收率为66-70%。操作示例2将甲苯加入干燥的不锈钢罐内，加热，蒸出甲苯直至馏出液为澄清。冷至35℃以下，加入氨基钠。升温至108℃，滴加吡啶。加毕，回流6h。冷至40℃加水，70℃搅拌1h。冷至30℃以下，分去水层（甲苯提取1次）。甲苯层用无水碳酸钠干燥。回收甲苯后，冷却固化得2-氨基吡啶。收率为65%。2-氨基吡啶的其他6-氨基烟酸在高于熔点的温度下熔融脱羧；由吡啶甲酰胺进行霍夫曼反应制取；通过2-溴吡啶氨解。工业生产中是向反应器中加入新制的氨基钠颗粒及甲苯，加热至110℃微有回流时，于搅拌下滴加吡啶，冷却控制反应速度，待反应缓慢后，继续加热搅拌回流3h；冷却至40℃加水分解，至反应物全部溶解时，趁热分去下层碱液，油层蒸去甲苯后，减压蒸馏，冷却后固化，得白色结晶，收率60%-63%。
