Participants

Reaction Steps

To a solution of (±)-3-({6-[1-(3-trifluoromethyl-phenylcarbamoyl)-1H-indol-5-yloxy]-pyrimidin-4-ylmethyl}-amino)-pyrrolidine-1-carboxylic acid tert-butyl ester (60 mg, 0.10 mmol) in THF (5 mL) acetyl chloride (12 mg, 0.15 mmol) and TEA (20 mg, 0.2 mmol) are added at 0° C. After 30 min, the mixture is diluted with EtOAc, washed with water, brine, and the organic layer is dried over Na2SO4, filtered, and condensed. The residue is separated by FCC (0-10%, 2 M NH3 in MeOH/DCM) to provide the title compound. MS (ESI) z 638.1 (M+1).
