Reaction Steps

To the solution of 2-(cyclohexylmethylamino)-5-fluorobenzo[d]thiazol-6-ol (25 mg, 0.089 mmol, 1.0 eq) in 2 mL of NMP was added 4-chloro-N-methylpicolinamide (18 mg, 0.107 mmol, 1.2 eq) and cesium carbonate (86 mg, 0.267 mmol, 3.0 eq) at room temperature. The reaction mixture was stirred at 85° C. for 12 hours, thereafter the mixture was purified on reverse phase HPLC giving 1.6 mg of product as TFA salt in ca. 3.5% yield. LC/MS (m/z) [415.1] (MH+)
