4-(3-chloroanilino)-6-ethoxycarbonyl-7H-pyrrolo[2,3-d]pyrimidine → 4-(3-Chloro-anilino)-6-[N-(3-methyl-but-1-yl)-carbamoyl]-7H-pyrrolo[2,3-d]pyrimidine

Participants

Reaction Steps

95 mg (0.30 mmol) of 4-(3-chloro-anilino)-6-ethoxycarbonyl-7H-pyrrolo[2,3-d]pyrimidine in 1 ml of (3-methyl-but-1-yl)-amine are heated at 80° C. for 12 hours. The reaction mixture is concentrated by evaporation, the residue is dissolved in THF, concentrated by evaporation again, stirred with diethyl ether and filtered, yielding the title compound; m.p. 304-306° C.; FAB-MS: (M+H)+ =358.
