Participants

Reaction Steps

(±)-3-({6-[1-(3-Trifluoromethyl-phenylcarbamoyl)-1H-indol-5-yloxy]-pyrimidin-4-ylmethyl}-amino)-pyrrolidine-1-carboxylic acid tert-butyl ester (20 mg, 3.30 mmol) is stirred in a solution of DCM (2 mL) and TFA (0.5 mL) overnight. After removal of solvents, the residue is quenched with saturated aqueous sodium bicarbonate. The mixture is then extracted with EtOAc (3×) and the combined organic layers are washed with water, brine, dried with Na2SO4, filtered, and condensed. The residue is purified by FCC (0-10% 2 M NH3 in MeOH/DCM) to provide the title compound. MS (ESI) m/z 496.8 (M+1); 1H NMR (400 MHz, MeOD) δ ppm 8.65 (s, 1 H), 8.36 (d, J=8.84 Hz, 1 H), 8.06 (s, 1H), 7.95 (d, J=3.54 Hz, 1 H), 7.88 (s, 1 H), 7.57 (t, J=7.83 Hz, 1 H), 7.44 (d, J=7.83 Hz, 1 H), 7.42 (d, J=2.27 Hz, 1 H), 7.03-7.13 (m, 2 H), 6.75 (d, J=3.79 Hz, 1 H), 3.80-3.85 (m, 2 H), 2.81-3.02 (m, 3 H), 2.52-2.75 (m, 2 H), 2.19-2.35 (m, 2 H).
