Reaction Steps

To a 25 mL pear flask were added 2-amino-4-chloro-6-methylpyrimidine-5-carbonitrile (70.7 mg, 0.419 mmol) and tert-butyl (S)-4-(5-(1-aminoethyl)-1-methyl-1H-pyrrolo[3,2-b]pyridin-6-yl)-1,4-diazepane-1-carboxylate (87 mg, 0.23 mmol) in DMSO (1.2 mL). Triethylamine (162 μL, 1.17 mmol) was added to the mixture which was then heated to 90° C. After 1 hour, UPLC indicated the reaction was complete. The reaction mixture was partitioned between saturated NaHCO3 and ethyl acetate. The aqueous layer was extracted with ethyl acetate. The organic layers were combined, dried over MgSO4, filtered, and concentrated. The residue was purified by liquid chromatography (SiO2, 25-100% EtOAc/heptanes gradient) to give the title compound as a foam (81 mg, 69%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.35-1.52 (m, 12H), 1.91 (s, 2H), 2.24 (s, 3H), 2.95-3.19 (m, 4H), 3.57 (d, J=5.56 Hz, 4H), 3.80 (br s, 1H), 5.90-6.01 (m, 1H), 6.49 (d, J=3.28 Hz, 1H), 6.95 (br s, 4H), 7.55 (d, J=3.03 Hz, 1H), 7.81 (d, J=6.82 Hz, 1H); ESI-MS m/z [M+H]+ calc'd for C26H35N9O2, 506. found 506.
