Procedure

A solution of (±)-1-(sec-butyl)-6-chloro-N-((4-methoxy-6-methyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-2-methyl-1H-indole-3-carboxamide (Compound 185) (50 mg, 0.12 mmol), pyridine-3-ylboronic acid (22 mg, 0.18 mmol), tricyclohexylmethane (7 mg, 0.024 umol), K3PO4 (120 mg, 0.60 mmol), Tris(dibenzylideneacetone)dipalladium(0)(10 mg), water (1 mL) and 1,4-dioxane (4 mL) was stirred under N2 at 100° C. for 16 h. The reaction was then allowed to cool to rt and the mixture was diluted with water and dichloromethane, the aqueous layer was extracted with dichloromethane. The organic layers were dried with Na2SO4 and evaporated. The residue was purified by preparative-HPLC (Instrument: Gilson 215; Column: Gemini C18 10u 150*25 mm; Mobile phase A: Water (0.0225% HCl v/v); Mobile phase B: Acetonitrile(neutral); Gradient: 42-62(B %); Flowrate: 25 ml/min) The collected fractions were combined and lyophilized to give 1-(sec-butyl)-N-((4-methoxy-6-methyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-2-methyl-6-(pyridine-3-yl)-1H-indole-3-carboxamide as a yellow solid (3.2 mg, yield 5.7%).
