Pyrimidin‐2‐yl sulfonates, as an efficientreaction partner, which can be easily prepared from cheap commercial materials, were coupled with phenols and anilines to give a wide array of C2‐aryloxy‐ and arylaminopyrimidines in good to excellent yields under mild reaction conditions.

The Biginelli 3,4-dihydropyrimidin-2(1H)-one was converted to various C2-multifunctionalized pyrimidines via the dehydrogenation and Mitsunobu reaction using amines, alcohols, phenols and carboxylic acids as nucleophiles. A possible mechanism was also proposed to rationalize the formation of products.
