Procedure

The title compound 5-(3-(4-(1H-pyrazolo[3,4-d]pyrimidin-1-yl)phenoxy)propyl)-2-(1-(benzo[d]thiazol-2-ylcarbamoyl)-1,2,3,4-tetrahydroquinolin-7-yl)thiazole-4-carboxylic acid (23) was prepared by the following procedure: To ethyl 5-(3-(4-(1H-pyrazolo[3,4-d]pyrimidin-1-yl)phenoxy)propyl)-2-(1-(benzo[d]thiazol-2-ylcarbamoyl)-1,2,3,4-tetrahydroquinolin-7-yl)thiazole-4-carboxylate (23I) (120 mg, 0.17 mmol) was added MeOH and THF. LiOH (20 mg, 0.85 mmol) was dissolved in water and added to the reaction mixture. The reaction mixture was stirred and heated at 60° C. for two hours. The reaction was cooled and put in refrigerator overnight. The precipitate was transferred to a centrifuge tube and centrifuged down at 17,000 RPM. The precipitate was washed water. Then the precipitate was added to acetonitrile and water and lyophilized to give 69 mg (59%) of the desired product 5-(3-(4-(1H-pyrazolo[3,4-t]pyrimidin-1-yl)phenoxy)propyl)-2-(1-(benzo[d]thiazol-2-ylcarbamoyl)-1,2,3,4-tetrahydroquinolin-7-yl)thiazole-4-carboxylic acid (23): 1H NMR (400 MHz, DMSO) δ 9.44 (s, 1H), 9.10 (s, 1H), 8.61 (s, 1H), 8.04 (d, J=8.7, 2H), 7.66 (s, 1H), 7.45 (d, J=34.2, 2H), 7.20 (t, J=18.3, 5H), 4.12 (s, 3H), 3.95 (s, 3H), 2.79 (s, 2H), 2.16 (s, 3H), 1.89 (s, 2H), −0.00 (s, 3H).
