Procedure

Cs2CO3 (85 mg, 0.26 mmol) is added to a solution of 1-[1-(2-chloro-6-ethyl-pyrimidin-4-yl)-5-(2,6-dimethyl-phenyl)-1H-pyrrolo[2,3-c]pyridin-3-yl]-2-ethyl-butan-1-ol (100 mg, 0.22 mmol) in MeOH (4 mL). The mixture is heated at 60° C. for 30 min. The mixture is concentrated under reduced pressure, diluted with water (5 mL), and the product is extracted with DCM. The combined organic extracts are washed with brine, dried (Na2SO4), and concentrated under reduced pressure. Chromatography of the residue silica gel (hexane-EtOAc, 1:1) gives 1-[5-(2,6-dimethyl-phenyl)-1-(6-ethyl-2-methoxy-pyrimidin-4-yl)-1H-pyrrolo[2,3-c]pyridin-3-yl]-2-ethyl-butan-1-ol as colorless oil: 1H NMR (CDCl3) 10.18 (s, 1H), 8.39 (s, 1H), 7.54 (s, 1H), 7.27-7.12 (m, 3H), 6.41 (s, 1H), 5.00 (d, J=6 Hz, 1H), 4.12 (s, 3H), 2.78 (dd, J=7, 15 Hz, 2H), 2.075 (s, 6H), 1.39 (t, J=7 Hz, 2.05-1.26 (m, 5H), 0.92 (t, J=7 Hz, 6H); LCMS (1) m/z 459.33 (2.65 min).
