A method for synthesizing levomethadone hydrochloride including producing (R)-2-(dimethylamino)propan-1-ol by reducing N,N-dimethyl-D-alanine using borax, forming (R)-1-chloro-N,N-dimethylpropane-2-amine hydrochloride by chlorinating the (R)-2-(dimethylamino)propan-1-ol, synthesizing levomethadone nitrile hydrochloride by mixing the (R)-1-chloro-N,N-dimethylpropane-2-amine and diphenylacetonitrile with potassium t-butoxide and producing levomethadone hydrochloride by exposing the levomethadone nitrile hydrochloride to a Grignard reagent.
一种合成左旋美沙酮盐酸盐的方法,包括通过使用硼砂还原N,N-二甲基-D-丙氨酸生成(R)-2-(二甲氨基)丙醇,通过氯化(R)-2-(二甲氨基)丙醇形成(R)-1-氯-N,N-二甲基丙烷-2-胺盐酸盐,通过混合(R)-1-氯-N,N-二甲基丙烷-2-胺盐酸盐和二苯基乙腈与钾叔丁氧化物合成左旋美沙酮腈盐酸盐,通过将左旋美沙酮腈盐酸盐暴露于格氏试剂生成左旋美沙酮盐酸盐。
