A solution of 5-(2,3-dihydro-1H-indol-5-yl)-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine 2HCl (150 mg, 0.443 mmol), [6-(trifluoromethyl)-2-pyridinyl]acetic acid (91 mg, 0.443 mmol), HATU (169 mg, 0.443 mmol), and DIEA (0.310 mL, 1.774 mmol) in N,N-Dimethylformamide (DMF) (3 mL) were stirred overnight at room temperature. LCMS analysis at this time indicated good conversion, so the reaction mixture was poured into water (10 mL) and stirred for 30 min. The resulting precipitate was collected by filtration, dried at the pump for an hour, adsorbed onto silica and purified by flash chromatography (0-10% MeOH in EtOAc) to afford 7-methyl-5-(1-{[6-(trifluoromethyl)-2-pyridinyl]acetyl}-2,3-dihydro-1H-indol-5-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine (80 mg, 39.9% yield) as a beige solid. LC-MS (ES) m/z=453 [M+H]+. 1H NMR (400 MHz, DMSO-d6) δ ppm 3.26 (t, J=8.34 Hz, 2H), 3.74 (s, 3H), 4.21 (s, 2H), 4.31 (t, J=8.46 Hz, 2H), 5.85-6.26 (m, 2H), 7.23 (d, J=8.34 Hz, 1H), 7.26 (s, 1H), 7.34 (s, 1H), 7.71 (d, J=7.83 Hz, 1H), 7.83 (d, J=7.58 Hz, 1H), 8.05-8.13 (m, 2H), 8.15 (s, 1H).
