실험 절차

A mixture of (R)-6-(5-isopropyl-2-methylphenyl)-2-(3-methyl-1-tosyl-1H-indol-4-yl)-4-(3-methylpiperazin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (52 mg, 0.080 mmol), prepared in a manner similar to that described in Example 25, methanesulfonyl chloride (0.01 mL, 0.096 mmol) and DIEA (0.042 mL, 0.240 mmol) in DCM (3 mL) was stirred at rt for 30 min. The reaction mixture was diluted with EtOAc, washed successively with sat NaHCO3, and brine, dried over Na2SO4 and concentrated. The resulting residue was purified via FCC (5-50% EtOAc/heptane) to provide (R)-6-(5-isopropyl-2-methylphenyl)-2-(3-methyl-1-tosyl-1H-indol-4-yl)-4-(3-methyl-4-(methylsulfonyl)piperazin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine. MS (ESI+) m/z 727.4 (M+H)+. To a solution of (R)-6-(5-isopropyl-2-methylphenyl)-2-(3-methyl-1-tosyl-1H-indol-4-yl)-4-(3-methyl-4-(methylsulfonyl)piperazin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (40 mg, 0.055 mmol) in MeOH (4 mL), NH4OH (0.325 mL, 8.25 mmol) and KOH (27.8 mg, 0.495 mmol) was added. The mixture was heated in a microwave reactor 100° C. for 1 h. The mixture was then filtered and concentrated. The resulting residue was purified via FCC (0-45% EtOAc/heptane) to provide (R)-6-(5-isopropyl-2-methylphenyl)-2-(3-methyl-1H-indol-4-yl)-4-(3-methyl-4-(methylsulfonyl)piperazin-1-yl)-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine. 1H NMR (400 MHz, DMSO-d6) δ ppm 10.91 (d, J=2.02 Hz, 1 H) 7.40-7.43 (m, 1 H) 7.24 (dd, J=7.33, 1.01 Hz, 1 H) 7.09-7.16 (m, 3 H) 7.02 (d, J=1.26 Hz, 1 H) 6.87 (dd, J=7.83, 1.26 Hz, 1 H) 4.03-4.16 (m, 3 H) 3.70-3.84 (m, 2 H) 3.56 (d, J=12.88 Hz, 1 H) 3.33-3.42 (m, 2 H) 3.23-3.28 (m, 1 H) 3.14 (dd, J=12.88, 3.54 Hz, 1 H) 2.92-3.06 (m, 6 H) 2.79-2.90 (m, 1H) 2.22 (s, 3 H) 2.03 (s, 3 H) 1.32 (d, J=6.82 Hz, 3 H) 1.19 (dd, J=6.95, 1.89 Hz, 6 H); MS (ESI+) m/z 573.4 (M+H)+.
