実験手順

Another particularly useful process is for manufacturing 4-tert.butyl-N-6-(2-hydroxy-ethoxy)-5-(2-methoxy-phenoxy)-2-(pyrimidin-2-yl)-pyrimidin-4-yl-benzenesulphonamide, This process comprises manufacturing 2-cyanopyrimidine by reacting 2-chloropyrimidine with an alkali cyanide in the presence of 1-azabicyclo[2,2,2]octane or 1,4-diazabicyclo[2,2,2]octane. The 2-cyano pyrimidine is then converted by means of NH3 /NH4Cl in a sodium methanolate/methanol solution into pyrimidin-2-carboxamidine hydrochloride. The pyrimidine-2-caroboxamidine hydrochloride is then converted in the presence of sodium methanolate with diethyl (o-methoxy-phenoxy-malonate) into rac-5-(2-methoxy-phenoxy)-2-pyrimidin-2-yl-tetrahydro-pyrimidin-4,6-dione. This product is then reacted with N,N-diisopropyl-N-ethylamine and phosphorus pentachloride to give 4,6-dichloro-5-(2-methoxy-phenoxy)-2,2'-bipyrimidine. This in turn is reacted with p-tert.butylbenzenesulphonamide to give 4-tert.butyl-N-6-chloro-5-[2-(2-methoxy-phenoxy)-2-(pyrimidin-2-yl)-pyrimidin-4-yl]-benzenesulphonamide which is reacted with sodium ethylene glycolate to give 4-tert.butyl-N-6-(2-hydroxy-ethoxy)-5-(2-methoxy-phenoxy)-2-(pyrimidin-2-yl)-pyrimidin-4-yl-benzenesulphonamide.
