An intermediate compound is disclosed that is useful in the preparation of a lipid-peroxidation inhibiting substance and that is selected from the group consisting of: 2,4-bis[1-adamantylamino]-6-(1-piperazinyl)pyrimidine; and 4,6-bis(1-adamantylamino)-2-(1-piperazinyl)pyrimidine; or a pharmaceutically acceptable acid addition salt thereof.
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
