実験手順

A mixture of methyl 1-benzyl-6-methyl-7-oxo-4-(((trifluoromethyl)sulfonyl)oxy)-6,7-dihydro-1H-pyrrolo[2,3-c]pyridine-5-carboxylate (7.5 g, 16.9 mmol), 4-chlorophenylboronic acid (3.89 g, 23.64 mmol) and Na2CO3 (7.52 g, 70.9 mmol) in 1,4-Dioxane (100 mL) and Water (20 mL) degassed with N2 for 15 minutes. The mixture was treated with palladium tetrakis (1.024 g, 0.887 mmol) and then stirred at 90° C. under N2 atmosphere overnight. The mixture was diluted with water and then extracted with Ethyl acetate. The combined extracts were washed with brine, dried over Na2SO4, filtered and concentrated. The residue was purified on silica gel (0-40% ethyl acetate/hexanes) to afford methyl 1-benzyl-4-(4-chlorophenyl)-6-methyl-7-oxo-6,7-dihydro-1H-pyrrolo[2,3-c]pyridine-5-carboxylate (6.4 g, 15.7 mmol, 93% yield) as a pale yellow solid. 1H NMR (400 MHz, CHLOROFORM-d) ppm 7.40 (s, 2H) 7.31-7.37 (m, 4H) 7.23-7.27 (m, 2H) 7.05 (d, J=2.93 Hz, 1H) 6.12 (d, J=2.93 Hz, 1H) 5.87 (s, 2H) 3.62 (s, 3H) 3.61 (s, 3H); LCMS (m/z) ES+=407 (M+1).
