To a stirred solution of methyl 4-(1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)pyrrolidin-3-ylcarbamoyl)-2-hydroxybenzoate in 5 mL of THF and 5 mL of methanol was added a solution of 1N NaOH (5 mL) at room temperature. After the addition, the reaction was stirred at this temperature for 16 hours. The solvent was evaporated and the residue was diluted with water and adjusted to pH=2 by HCl (aq.). The suspension was filtered and dried. The crude was purified by preparative HPLC (Gemini 5u C18 150×21.2 mm; inject volume: 3 ml/inj, flow rate: 20 ml/min; wavelength: 214 nm and 254 nm; the gradient conditions are: 20% acetonitrile/80% water (0.1% TFA V/V) initially, and then proceed to 45% acetonitrile/55% water (0.1% TFA V/V) in a linear fashion after just 9 min.) to give 4-(1-(7-(3,4-dimethoxyphenylamino)thiazolo[5,4-d]pyrimidin-5-yl)pyrrolidin-3-ylcarbamoyl)-2-hydroxybenzoic acid (15 mg, 14% over two steps). 1H NMR (300 MHz, DMSO): δ 9.72 (s, 1H), 8.85 (s, 1H), 8.76 (d, 1H, J=6.0 Hz), 7.86 (s, 1H), 7.84 (s, 1H), 7.43-7.37 (m, 3H), 6.92 (d, 1H, J=8.4 Hz), 4.56 (brs, 1H), 3.77-3.73 (m, 11H), 2.27-2.23 (m, 1H), 2.09-2.07 (m, 1H). LC-MS: 537 [M+H]+, tR=1.37 min. HPLC: 99.62% at 214 nm, 99.22% at 254 nm, tR=3.53 min.
