To a solution of 2-[4-(4-acetyl-piperazin-1-yl)-phenylamino]-7-(1-ethyl-propyl)-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid methyl ester (16 mg, 0.034 mmol) in THF (1.5 mL) is added 2 N LiOH aqueous solution (1 mL). The reaction mixture is stirred for 36 h and concentrated in vacuo. The residue is purified by preparative HPLC to give 9.4 mg of 7-(1-ethyl-propyl)-2-(4-piperazin-1-yl-phenylamino)-7H-pyrrolo[2,3-d]pyrimidine-6-carboxylic acid.
