Reaction Steps

To the solution of 4-(2-((1R,2R)-2-aminocyclohexylamino)benzo[d]thiazol-6-yloxy)-N-methylpicolinamide (9 mg, 22 μmole) and triethylamine (11 μL, 80 μmole) in 300 μL of DMF was added acetic anhydride (5 μL, 50 μmole). 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 4-(2-((1R,2R)-2-acetamidocyclohexylamino)benzo[d]thiazol-6-yloxy)-N-methylpicolinamide (5.1 mg, 12 μmole) as white powder. ES/MS m/z 440.2 (MH+).
