Pivalic acid is a useful medium to effect the direct SNAr displacement of 2-methylthio-4-pyrimidinones with a variety of anilines. Products are easily isolated in good to excellent yields, and following chlorination, provide an opportunity to rapidly query structure-activity relationships at the 4-position of functionalized pyrimidines.
