In neat (no solvent); at 160℃; | General procedure: A mixture of compound 3 (0.2 g, 1.03 mmol) and the appropriate aniline (1.03 mmol) were reacted neat at 160 C for 10-120 minutes. The reaction mixture was cooled, dissolved in DCM and concentrated under reduced pressure to afford the desired product, which was used directly in the next step without further purification. |

216 mg | With N-ethyl-N,N-diisopropylamine; HATU; In N,N-dimethyl-formamide; at 20℃; for 18h;Inert atmosphere; | To a solution of intermediate (586 mg, 1.61 mmol), 4-chloro-3- fluoroaniline (281 mg, 1.93 mmol), and HATU (673 mg, 1.77 mmol) in DMF (8.0 mL) at room temperature under N2 atmosphere was added diisopropylethylamine (0.84 mL, 4.8 mmol). The resulting mixture was stirred at room temperature for 18 h then concentrated in vacuo. The resulting residue was taken up in EtOAc and quenched with H2O. The layers were separated, and the aqueous phase was extracted with EtOAc (3x). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated in vacuo. Flash chromatography (SiO2, 50:50 hexanes:EtOAc) afforded the product as a white solid (216 mg, 20% yield over 2 steps). 1H NMR (500 MHz, Chloroform-d) d 8.76 (s, 1H), 7.61 (d, J = 10.5 Hz, 1H), 7.30 (t, J = 8.4 Hz, 1H), 7.11- 7.04 (m, 1H), 4.59 (d, J = 4.2 Hz, 1H), 3.91 (s, 1H), 3.56 (d, J = 13.2 Hz, 1H), 3.05- 2.92 (m, 2H), 2.88 (dd, J = 13.4, 4.3 Hz, 1H), 2.78 (td, J = 12.4, 3.5 Hz, 1H), 1.52 (s, 9H); 13C NMR (126 MHz, CDCl3) d 174.33, 147.70, 143.90, 139.16, 129.72, 127.25, 125.47, 119.69, 117.66, 114.46, 52.08, 43.73, 38.55, 29.84; IR (ATR) vmax 3285, 2925, 2850, 1653, 1525, 1321, 1154, 983, 948, 826, 790, 506 cm-1; AMM 492.1708 (ESI) m/z [calc for C24H28ClFN3O5 (M+H)+ 492.1702]. |
