Reaction Steps

5-(6-Aminomethyl-pyrimidin-4-yloxy)-indole-1-carboxylic acid (4-fluoro-3-trifluoromethyl-phenyl)-amide (52.5 mg, 0.117 mmol) is dissolved in DCM (5 mL) at 0° C. DIEA (0.025 mL, 0.143 mmol) is added followed by 4-bromo-butyryl chloride (0.020 mL, 0.172 mmol). The reaction is stirred for 30 min before being diluted with ethyl acetate and washed with water. The organic layer is removed, dried, and concentrated to provide the title compound. MS (ESI) m/z 595.6 (M+1). 110-B. 5-[6-(2-Oxo-pyrrolidin-1-ylmethyl)-pyrimidin-4-yloxy]-indole-1-carboxylic acid (4-fluoro-3-trifluoromethyl-phenyl)-amide.
