A preparation of ropinirole hydrochloride (by machine translation)
The invention belongs to the technical field of pharmaceutical chemistry and organic chemistry, and in particular relates to a preparation of ropinirole hydrochloride. The invention synthesizes a brand-new compounds: compound 4, and the compound as raw materials to make the ropinirole hydrochloride, the specific method is: the compound 4 dissolved in ethanol/methanol/ethyl acetate in one or several, adding Pd/C, reaction to obtain compound 5; the compound 5: to methyl chloride: pyridine=1: 1.2: 1.2 dissolved in dichloromethane/chloroform/1, 2 – dichloroethane/pyridine in one or several of, after the reaction compound 6; the compound 6: NaI: two-propylamine=1:1: 1.2 dissolved in DMF/DMSO/Toluene in one or several, react to Requip; containing hydrochloric acid of the ropinirole is dissolved in 1, 4 dioxane, the pressure of the ropinirole hydrochloride. The present invention provides a new method of preparation of ropinirole hydrochloride, step is simple and convenient, raw material is simple and easy to obtain, in the production can be put into actual use.
