Procedure

A round bottom flask was charged with a magnetic stir bar, 1-[1-(3-Bromo-phenyl)-ethyl]-2-methyl-1H-indole-3-carboxylic acid (4,6-dimethyl-2-oxo-2,3-dihydro-pyridin-3-ylmethyl)-amide (Step 8) (20 mg, 0.04 mmol), 4-Chloro-pyrimidine (6.95 mg, 0.06 mmol), potassium carbonate (10.9 mg, 0.08 mmol), 1,1′-Bis(diphenylphosphino)ferrocene palladium dichloride (44 mg, 0.06 mmol) and 1,4-dixoane/H2O (4:1, 8 mL). The mixture was purged and placed under N2 and stirred heated to reflux with stirring overnight. The reaction was then allowed to cool to rt and the mixture was concentrated in vacuo. The resulting residue was purified by preparative-HPLC (Column: YMC-Actus Triart C18150*30 mm*5 um; Mobile phase A: water with 0.1% HCl solution; Mobile phase B: MeCN; column temperature: 30° C.; Gradient: 35-65% B). The collected fractions were combined and lyophilized to afford the title compound (6.3 mg, yield 35%) LCMS (M+H+) m/z: calc'd 491.23. found 492.0; 1H NMR (400 MHz, MeOD-d4) δ 9.2 (s, 1H), 8.85-8.54 (d, 2H), 8.14-8.06 (m, 2H), 7.78-7.72 (m, 1H), 7.58-7.54 (t, 1H), 7.44-7.42 (d, 1H), 7.15-7.12 (d, 1H), 7.04-7.01 (t, 2H), 7.01-6.79 (t, 1H), 6.8 (s, 1H), 6.14-6.12 (t, 1H), 4.88 (m, 2H), 4.67 (s, 1H), 2.73 (s, 3H), 2.6 (s, 3H), 2.47 (s, 3H), 2.08-2.07 (d, 3H).
