Procedure
To a stirred solution of 4-(5-bromo-3,3-dimethyl-6-(4-morpholinyl)-2,3-dihydro-1H-pyrrolo[3,2-b]pyridin-1-yl)-7-fluoro-3-methyl-2-(2-pyridinyl)quinoline (61 mg, 0.111 mmol) in NMP (1.5 mL) was added tri-n-butyltin cyanide (35.2 mg, 0.111 mmol), XPhos precatalyst (16.3 mg, 0.022 mmol) and heated at 140° C. for 2 h in the microwave. After this time the reaction was partitioned between EtOAc (60 mL) and water (30 mL). The separated organic layer was dried over MgSO4, filtered and evaporated in vacuo. Purification by reverse phase HPLC (10 to 60% acetonitrile water) gave 1-(7-fluoro-3-methyl-2-(2-pyridinyl)-4-quinolinyl)-3,3-dimethyl-6-(4-morpholinyl)-2,3-dihydro-1H-pyrrolo[3,2-b]pyridine-5-carbonitrile. 1H NMR (400 MHz, chloroform-d) δ ppm 8.68-8.80 (1H, m), 7.84-7.99 (3H, m), 7.67 (1H, dd, J=9.2, 5.9 Hz), 7.44 (1H, ddd, J=6.9, 4.9, 1.9 Hz), 7.35 (1H, ddd, J=9.2, 8.0, 2.5 Hz), 5.74 (1H, s), 3.87 (2H, s), 3.79 (4H, t, J=4.7 Hz), 2.94-3.11 (4H, m), 2.40 (3H, s), 1.59 (3H, s), 1.53 (3H, s). Mass Spectrum (ESI) m/e=495.0 (M+1).
