2-[N-(2-hydroxyethyl)-N-methyl]-amino}-methylbenz- hydrol, which is used as an intermediate when producing 3,4,5,6-tetrahydro-5-methyl-1-phenyl-1 H-2,5-benz- oxazocine-hydrochloride or nefopam, which is used as a muscle relaxant, an analgesic or antidepressive drug, is advantageously made by reacting 2-chloromethylbenzophenone with methylethanolamine, and reducing the thus produced 2-[N-(2-hydroxyethyl)-N-methyl]-amino}- methylbenzophenone with sodium borohydride.
2-[N-(2-羟乙基)-N-甲基]-氨基}-甲基二苯甲酰基,在生产 3,4,5,6-四氢-5-甲基-1-苯基-1 H-2,5-苯噁唑嗪盐酸盐或用作肌肉松弛剂的奈福泮时用作中间体、2-[N-(2-hydroxyethyl)-N-methyl]-amino}- methylbenzophenone 与甲基乙醇胺反应,并用硼氢化钠还原生成 2-[N-(2-羟乙基)-N-甲基]-氨基}-甲基二苯甲酮。
