[00312] KHMDS 1 M in THF (0.758 mL) was added dropwise to a mixture of 5-bromo-6- chloro-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 44.2, 100 mg, 0.253 mmol) and tetrahydro-2 h-pyran-4-carbonitrile (42.1 mg, 0.379 mmol) in THF (2.5 mL), under a nitrogen atmosphere. The RM was stirred at -70C for 1 h, and allowed to warm to RT overnight. The RM was quenched with water and the solvent was evaporated off under reduced pressure to afford 5- bromo-6-(4-cyanotetrahydro-2 h-pyran-4-yl)-N-(4-(trifluoromethoxy)phenyl)nicotinamide, of which (50 mg, 0.106 mmol), Pd(Ph3P)4 (18 mg, 0.016 mmol), pyrimidin-5-ylboronic acid (20 mg, 0.159 mmol), K3PO4 (68 mg, 0.319 mmol) and toluene (1.3 mL) were added to a vial, which was sealed, evacuated / purged with argon. The RM was stirred at 110C for 3 h, diluted with MeOH, filtered through a cartridge PL-Thiol MP-Resin and concentrated the combined filtrates were evaporated to dryness under reduced pressure. The crude product was purified by preparative SFC (Column 2-EP, gradient: 6% to 11 % in 6 min) and lyophilized to afford an off- white powder. UPLC-MS (Condition 2) tR = 1.2 min, m/z = 469.9 [M+H]+; XH-NMR (600 MHz, DMSO-d6) delta ppm 2.00 (d, J=13.55 Hz, 2 H) 2.40 (td, J=13.08, 3.95 Hz, 2 H) 3.52 (t, J=12.14 Hz, 2 H) 3.94 (d, J=8.66 Hz, 2 H) 7.39 (d, J=8.66 Hz, 2 H) 7.86 (d, J=8.85 Hz, 2 H) 8.30 (s, 1 H) 8.96 (s, 2 H) 9.23 (d, J=1.13 Hz, 1 H) 9.32 (s, 1 H) 10.67 (s, 1 H).
The synthetic route of 4295-99-2 has been constantly updated, and we look forward to future research findings.
