Versuchsvorschrift

To the solution of (S)—N-methyl-4-(2-(piperidin-3-ylamino)benzo[d]thiazol-6-yloxy)picolinamide (13 mg, 30 μmol) and triethylamine (13 μL, 90 μmol) in 300 μL of DMA was added acetic anhydride (6 μl, 60 μmol). The reaction solution was stirred at room temperature for 1.5 hours. The crude reaction solution was purified on prep HPLC and evaporated in vacuo to give (S)-4-(2-(1-acetylpiperidin-3-ylamino)benzo[d]thiazol-6-yloxy)-N-methylpicolinamide (4.8 mg, 11 μmol) as white powder. ES/MS m/z 426.2 (MH+).
