A solution of 25 mg (0.6 mmol) of LiOH.H2O in 0.4 ml of H2O is added dropwise to a suspension of 95 mg (0.30 mmol) of 4-(3-chloro-anilino)-6-ethoxycarbonyl-7H-pyrrolo[2,3-d]pyrimidine in 0.7 ml of methanol. The reaction mixture is heated at boiling for 4.5 hours, then cooled in an ice-bath and acidified with 0.6 ml of 1 N HCl solution. Filtering and washing with water yield the title compound; HPLC: tRet (Grad20)=8.7; FAB-MS: (M+H)+ =289.
