실험 절차

To a solution of ethyl 4-(2-methyl-2H-indazol-6-yl)-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate in MeOH (2.0 mL) was added 2 M aqueous LiOH (1.1 mL) and the reaction mixture was heated at 60° C. for 17 hours. The reaction mixture was then acidified with AcOH and extracted with EtOAc (×3). The combined organic layers were then washed with brine, dried with sodium sulfate, filtered and concentrated under reduced pressure to give 4-(2-methyl-2H-indazol-6-yl)-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylic acid. No further purification was carried out. LRMS (ESI) calc'd for C21H26SiN5O3 [M+H]+: 424, found 424.
