Procedure

To the solution of (S)-6-(2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yloxy)-N-(piperidin-3-yl)benzo[d]thiazol-2-amine (7.6 mg, 18 μmol) and DIPEA (35 μL, 200 μmol) in 400 μL of NMP was added cyclopropanesulfonyl chloride (10 mg, 98 μmol). The reaction solution was stirred at 55 for 16 hours. The crude reaction solution was purified on prep HPLC and evaporated in vaccuo to give (S)—N-(1-(cyclopropylsulfonyl)piperidin-3-yl)-6-(2-(1-methyl-1H-pyrazol-4-yl)pyridin-4-yloxy)benzo[d]thiazol-2-amine (6.2 mg, 12 μmol as white powder. ES/MS m/z 511.2 (MH+).
