Versuchsvorschrift

To the solution of (S)—N-methyl-4-(2-(piperidin-3-ylamino)benzo[d]thiazol-6-yloxy)picolinamide (13 mg, 30 μmol) and DIPEA (17 μL, 100 μmol) in 300 μL of NMP was added 2-isocyanatopropane (5 μL, 50 μmol). The reaction solution was stirred at room temperature for 18 hours. The crude reaction solution was purified on prep HPLC and evaporated in vacuo to give (S)-4-(2-(1-(isopropylcarbamoyl)piperidin-3-ylamino)benzo[d]thiazol-6-yloxy)-N-methylpicolinamide (5.9 mg, 12 μmol) as white powder. ES/MS m/z 469.2 (MH+).
