To a solution of 6-(3-cyclopropyl-1-methyl-1H-pyrazol-5-yl)-2-(3,5-dimethyl-1H-indazol-4-yl)-4-(3-ethoxyazetidin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (30 mg, 0.060 mmol) in DCM (2 mL) was added N-chlorosuccinimide (9.64 mg, 0.072 mmol) at room temperature. The mixture was stirred for 30 min then concentrated. The residue was purified by reverse phase HPLC (C18, 10-100% acetonitrile-H2O with 0.1% NH4OH) to give 6-(4-chloro-3-cyclopropyl-1-methyl-1H-pyrazol-5-yl)-2-(3,5-dimethyl-1H-indazol-4-yl)-4-(3-ethoxyazetidin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine. 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.43 (d, J=8.46 Hz, 1H), 7.30 (d, J=8.59 Hz, 1H), 4.49 (dd, J=6.63, 9.41 Hz, 2H), 4.35-4.45 (m, 3H), 4.14 (dd, J=4.04, 10.36 Hz, 2H), 3.66 (s, 3H), 3.46-3.55 (m, 4H), 2.89 (t, J=5.68 Hz, 2H), 2.27 (s, 3H), 2.04 (s, 3H), 1.81-1.88 (m, 1H), 1.19 (t, J=7.01 Hz, 3H), 0.76-0.93 (m, 4H); MS (ESI+) m/z 533.4 (M+H)+.
