Procedure
A suspension of ethyl 3-amino-3-(1-methylcyclopentyl)propanoate, 33a, (0.20 g, 1.00 mmol), 5-fluoro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)-pyrrolo[2,3-b]pyridine, 25a (0.54 g, 1.20 mmol), and N,N-diisopropylethylamine (0.26 mL, 1.50 mmol) in THF (14.4 mL) was refluxed at 80° C. overnight. After removing the solvent in vacuo, the crude product was purified by silica gel chromatography (0-50% EtOAc/Hexanes gradient) to afford 300 mg of the desired product as a light yellow solid: 1H NMR (400 MHz, CDCl3) δ 8.49 (dd, J=9.0, 2.8 Hz, 1H), 8.46 (s, 1H), 8.23 (d, J=1.5 Hz, 1H), 8.02 (d, J=8.3 Hz, 2H), 7.99 (d, J=3.1 Hz, 1H), 7.20 (d, J=7.8 Hz, 2H), 5.23 (d, J=8.9 Hz, 1H), 4.80 (td, J=9.7, 3.6 Hz, 1H), 4.04 (q, J=7.1 Hz, 1H), 3.91 (q, J=7.1 Hz, 2H), 2.73-2.58 (m, 1H), 2.44 (dd, J=14.7, 9.6 Hz, 1H), 2.33-2.21 (m, 3H), 1.72-1.46 (m, 7H), 1.42-1.31 (m, 1H), 1.28 (t, J=6.1 Hz, 1H), 1.17 (dd, J=13.4, 6.2 Hz, 2H), 0.98 (t, J=7.1 Hz, 6H); LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, RT=4.25 minutes (M+H) 584.29.
