Participants

Reaction Steps

A mixture of 5-bromo-3-cyclopentyl-1H-pyrrolo[2,3-b]pyridine (31.8 mg, 0.12 mmol), 3-hydroxyphenylboronic acid (33.1 mg, 0.24 mmol) and 4.2 mg (5 mol %) of dichlorobis(triphenylphosphino)palladium(II) were placed in a vial and 0.8 ml of acetonitrile and 0.8 ml of a 2 m aqueous solution of sodium carbonate were added and the mixture irradiated in a Personal Chemistry® microwave reactor to 150° C. for 900 seconds. The resulting mixture was distributed between 15 mL of a Saturated aqueous solution, of sodium bicarbonate and 30 mL of dichloromethane. The organic phase was dried over sodium sulfate and evaporated. The crude was purified via silica gel chromatography using a gradient, of ethyl acetate in hexanes to give 3-(3-Cyclopentyl-1H-pyrrolo[2,3-b]pyridin-5-yl)-phenol (4.5 mg, 1.4% yield) as off white powder. 1H NMR (500 MHz, CD3OD) δ 8.36 (s, 1H), 8.14 (d, 2 Hz, 1H), 7.29 (t, 8 Hz, 1H), 7.19 (s, 1H), 7.10 (d, 7 Hz, 1H), 7.06 (s, 1H), 6.79 (dd, 2 Hz, 8 Hz, 1H), 2.1 (m, 2H), 1.94 (m, 2H), 1.8 (m, 4H), 1.37 (m, 1H). MS: m/z 279.1 [MH+].
