A novel process for preparing imidazopyran derivatives of the formula:
wherein R1 is halogen atom, hydrogen atom, C1 to C3 alkyl group, aryl group, or aryl group substituted by C1 to C3 alkyl group, by using dinitroimidazole and 2,3-epoxy-1-propanol as starting materials and being followed by five steps.
