Some novel 4-N-substituted terpenyl pyrimidines 5(a-d) and 7(a-g) have been synthesized using novel synthetic methods. The compounds were screened for in vivo antileishmanial screening. When compared to 4-thiomethoxy substituted pyrimidine 2 4-N-substituted terpenyl pyrimidines 5(a-d) and 7(a-g) were found inactive.
