The synthesis and structure-activity relationships of the 4- and 6-substituents of 2,4-diaminopyrimidine-based growth hormone secretagogue receptor (GHS-R) antagonists are described. Diaminopyrimidines with 6-norbornenyl (4n) and 6-tetrahydrofuranyl (4p) substitutents were found to exhibit potent GHS-R antagonism and good selectivity (～1000-fold) against dihydrofolate reductase.

A rapid synthesis of a series of 6-alkyl substituted-5-(4′ -amino-phenyl)-pyrimidine-2,4-diamines is described. These analogs were produced in good yields on moderate scale (ca. 8 g) without chromatography. Furthermore, the methodology described herein al
