Abstract

Abstract The synthesis of 2-(2-furyl) imidazo [1, 2-a] pyrimidine has been carried out. Azocoupling, nitrosation, and bromination by 1 mole of bromine occur at position 3 of the bicycle. Reaction with 2 mol of bromine gives the 3, 5‰-disubstituted derivative. Bromination using 1 mol of bromine in 40% hydrobromic acid and sulfonation occur initially at the 5‰ position of the furyl group.
