The pilot-plant synthesis of nevirapine analogue 1 is described. The compound was prepared in eight steps from substituted pyridine raw materials and 4-hydroxyquinoline. The key transformation involves a novel one-pot conversion of an arylhalide to arylacetic acid under palladium catalysis, followed by regioselective reduction via in situ generated BH3/THF to the arylethanol intermediate 2. All stages
描述了奈韦拉平类似物1的中试合成。由取代的吡啶原料和4-羟基喹啉分八步制备该化合物。关键的转化涉及在钯催化下将芳基卤化物一锅转化为芳酸,然后通过原位生成的BH 3 / THF选择性还原成芳基乙醇中间体2。所有阶段均以10-150千克规模进行。
