FIELD: chemistry. ^ SUBSTANCE: invention refers to Sertaconasole mononitrate process by reaction of 1-(2,4-dichlorphenyl)-2-(1H-imidazole-1-yl)ethanol and 3-bromomethyl-7-chlorbenzo[b]thiophene with tetrabutylammonium hydrosulphate and sodium hydroxide in toluene at 30-45C. Produced free base of Sertaconasole is transferred into Sertaconasole mononitrate monohydrate with the latter being transferred into Sertaconasole mononitrate. There is disclosed and characterised intermediate Sertaconasole mononitrate monohydrate. ^ EFFECT: method allows simplifying process technology considerably. ^ 6 cl, 5 dwg, 2 tbl, 2 ex |
