The present invention describes a novel process for the preparation of (6S)-(-)-5,6,7,8-tetrahydro-6-[propyl-(2-thienyl)ethyl]amino-1-naphthol (Rotigotine) comprising: (a) acetylating (S)-(-)-5-hydroxy-N-n-propyl-2-aminotetraline to afford the acetate; (b) reacting this acetate, (-)-5-acetoxy- N-n-propyl-2-aminotetraline, with 2-(2-thienyl)ethanol 2- nitrobenzenesulfonate; (d) hydrolyzing (6S)-(-)-1-acetoxy-5, 6,7,8- tetrahydro-6-[propyl-(2-thienyl)ethyl]amino-1-naphthalene to afford (6S)-(- )-5, 6, 7, 8-tetrahydro-6-[propyl-(2-thienyl)ethyl]amino-1-naphthol (Rotigotine) and (d) purifying rotigotine either by the acetylation reaction and subsequent hydrolysis of the formed acetate or by salification of rotigotine through hydrochloride or hydrobromide formation and subsequent base release. Rotigotine is a dopamine agonist and is indicated for the treatment of Parkinson's disease.
本发明描述了一种新型制备(6S)-(-)-5,6,7,8-四氢-6-[丙基-(2-噻吩基)乙基]氨基-1-萘酚(洛地静)的方法,包括:(a) 乙酰化(S)-(-)-5-羟基-N-丙基-2-氨基四氢萘制得醋酸盐;(b) 用2-(2-噻吩基)乙醇2-硝基苯磺酸盐反应此醋酸盐,(-)-5-乙酰氧基-N-丙基-2-氨基四氢萘;(d) 水解(6S)-(-)-1-乙酰氧基-5,6,7,8-四氢-6-[丙基-(2-噻吩基)乙基]氨基-1-萘烯制得(6S)-(-)-5,6,7,8-四氢-6-[丙基-(2-噻吩基)乙基]氨基-1-萘酚(洛地静),(d) 通过醋酸化反应和随后的水解制备洛地静,或通过盐酸或溴化氢盐的形成和随后的碱释放来盐化洛地静。洛地静是一种多巴胺激动剂,适用于帕金森病的治疗。
