Versuchsvorschrift
A mixture of 4-chloro-6-(3,4-dimethoxy-phenyl)-2-methanesulfonyl-pyrimidine [5.05 g, 0.0154 mol, Intermediate (49)] in ethylene glycol dimethyl ether (100 mL) is chilled to 0° C. and added 25 wt % sodium methoxide in MeOH (1.32 mL, 0.0231 mol). After 15 minutes the reaction is allowed to warm to ambient temperature and stirred overnight. The mixture is concentrated to afford 4-chloro-6-(3,4-dimethoxy-phenyl)-2-methoxy-pyrimidine [4.3 g, 100%, Intermediate (50)]
