Reaction Steps

A mixture of 4-(6-(2-(3-(2-methylpiperidin-1-yl)propylamino)-6-(trifluoromethyl)pyridin-3-yl)pyrimidin-4-yloxy)benzo [d]thiazol-2-amine trifluoroacetic acid salt, Example 80, (29 mg, 0.052 mmol), potassium carbonate (35 mg, 0.253 mmol) and acetic anhydride (2 mL) was heated at 90° C. in a microwave synthesizer for 10 min. to give MS (ESI, pos. ion.) m/z: 658 (M+1). The reaction mixture was dissolved in DCM (10 mL), filtered, and concentrated in vacuo. The residue was purified by reverse phase HPLC (Phenomenex Prodigy 5μ ODS-3 100 Å column, gradient: 20-100% CH3CN (0.1% TFA)/H2O (0.1% TFA) over 15 min) to give the title compound as a light-yellow amorphous solid. MS (ESI, pos. ion.) m/z: 700 (M+1).
