5-(6-Hydroxymethyl-pyrimidin-4-yloxy)-indole-1-carboxylic acid (3-trifluoromethyl-phenyl)-amide → 5-(6-Formyl-pyrimidin-4-yloxy)-indole-1-carboxylic acid (3-trifluoromethyl-phenyl)-amide

Participants

Reaction Steps

To a suspension of 5-(6-Hydroxymethyl-pyrimidin-4-yloxy)-indole-1-carboxylic acid (3-trifluoromethyl-phenyl)-amide (310 mg, 0.724 mmol) in DCM (10 mL), DMP (337 mg, 0.795 mmol) is added. The reaction mixture is stirred at rt until complete as seen by LCMS (about 1 h). The reaction is quenched with saturated aqueous NaHCO3 and extracted with EtOAc (3×10 mL). The combined organic layers are then washed by brine, dried (Na2SO4), filtered and concentrated. The crude residue is purified by FCC (0-40% EtOAc/Heptane) to provide the title compound. MS (ESI) m/z 443.1 (M+1); 1H NMR (400 MHz, MeOD) δ ppm 8.84 (d, J=1.01 Hz, 1 H), 8.36 (d, J=9.09 Hz, 1 H), 8.06 (s, 1 H), 7.96 (d, J=3.79 Hz, 1 H), 7.89 (s, 1 H), 7.55-7.60 (m, 1 H), 7.45 (s, 1 H), 7.40 (d, J=1.01 Hz, 2 H), 7.44 (d, J=2.53 Hz, 1 H), 7.13 (dd, J=8.97, 2.40 Hz, 1 H), 6.76 (d, J=3.79 Hz, 1 H), 2.66 (s, 3 H).
