実験手順

To the solution of 6-(2-chloropyridin-4-yloxy)-2-(methylsulfinyl)benzo[d]thiazole (26 mg, 80 μmol) in 400 μL of NMP was added (R)-2-amino-4-methylpentan-1-ol (33 μL, 250 μmol) and DIPEA (17 μL, 100 μmol). The reaction solution was stirred at 100° C. for 18 hours. The crude reaction solution was purified on prep HPLC and evaporated in vacuo to give (R)-2-(6-(2-chloropyridin-4-yloxy)benzo[d]thiazol-2-ylamino)-4-methylpentan-1-ol (12 mg, 31 μmol) as powder. ES/MS m/z 378.1 (MH+).
