Procedure

To the reaction solution of isobutyric acid (4 μl, 40 μmol), HATU (15 mg, 40 μmol) and DIEA (14 μL, 80 μmol) in 400 μL of DMA was added (S)—N-methyl-4-(2-(piperidin-3-ylamino)benzo[d]thiazol-6-yloxy)picolinamide (13 mg, 30 μmol) and DIPEA (6 μL, 30 μmol). The reaction solution was stirred at room temperature for 16 hours. The crude reaction solution was purified on prep HPLC and evaporated in vacuo to give (S)-4-(2-(1-isobutyrylpiperidin-3-ylamino)benzo[d]thiazol-6-yloxy)-N-methylpicolinamide (6.8 mg, 15 μmol) as white powder. ES/MS m/z 454.2 (MH+).
