To a solution of 4-chloro-6-(3-isopropyl-1-methyl-1H-pyrazol-5-yl)-2-(3-methyl-1H-indol-4-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (50 mg, 0.123 mmol) in N,N-dimethylacetamide (1.5 mL), was added diisopropylethylamine (0.15 mL, 0.86 mmol) and (S)-2-methylpiperidine (37 mg, 0.37 mmol). The reaction was stirred and heated to 125° C. for 24 h. After cooling, the mixture was directly purified via HPLC ((0.1% ammonium hydroxide in acetonitrile)/water=35%-100%). 1H NMR (400 MHz, CD2Cl2) δ ppm 8.23 (br. s., 1 H), 7.42 (d, J=8.1 Hz, 1 H), 7.33 (d, J=8.1 Hz, 1 H), 7.16-7.26 (m, 1 H), 7.04 (s, 1 H), 5.69 (s, 1 H), 4.06-4.16 (m, 1 H), 3.90-4.06 (m, 2 H), 3.67 (s, 3 H), 3.53 (d, J=13.4 Hz, 1 H), 3.29-3.40 (m, 2 H), 3.16-3.29 (m, 1 H), 3.10 (d, J=4.5 Hz, 2 H), 2.85 (dt, J=13.8, 6.9 Hz, 1 H), 2.10 (s, 3 H), 1.74-1.91 (m, 2 H), 1.65-1.74 (m, 2 H), 1.48-1.65 (m, 2 H), 1.22 (d, J=6.8 Hz, 6 H); MS (ESI+) m/z 484.4 (M+H)+.
