Chemoselective SNAr reactions of 4,6-dichloro-2-(methylsulfonyl)pyrimidine and several related electrophiles with amines and their derivatives are described. In the presence of weak bases anilines and secondaryaliphatic amines selectively displace the chloride group. Deprotonated anilines and their carbonyl derivatives displace the sulfone group. Sterically and electronically unbiased primaryaliphatic amines
Amine substituted pyrimidine compounds and forms thereof that inhibit the function and reduce the level of B-cell specific Moloney murine leukemia virus integration site 1 (Bmi-1) protein and methods for their use to inhibit Bmi-1 function and reduce the level of Bmi-1 to treat a cancer mediated by Bmi-1 are described herein.

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.
