Pyrrolopyrimidine derivatives represented by the formula:
wherein R3 represents a hydrogen atom or a C1-C5 alkyl group, R4 and R5 are identical or different, and each represents a hydrogen atom or a C1-C5 alkyl group; X4 represents a hydroxyl group, a chlorine atom, a bromine atom, or an iodine atom; and X5 represents a halogen atom, a C1-C5 alkyl group, a C1-C5 alkoxy group, a C1-C5 alkylthio group, a trifluormethyl group, or a trifluoromethoxy group. These pyrrolopyrimidine derivatives are useful as intermediates for the preparation of carbamoyl tetrahydropyridine derivatives which are efficacious against CRF-related diseases.
