PROCEDURE
实验过程
1,1-Dimethylethyl (2S)-4-({4-[[(6-chloro-3-pyridinyl)carbonyl](methyl)amino]phenyl}methyl)-2-methyl-1-piperazinecarboxylate (D54) (0.1 g, 0.218 mmol) and 2-fluorophenol (0.025 g, 0.436 mmol) were dissolved in DMF (5 mL). Potassium carbonate (0.06 g, 0.436 mmol) was added and the mixture was heated to 80° C. overnight then at 130° C. for 7 h. The mixture was left to stand at room temperature overnight and the solvent removed under vacuum. The residue was partitioned between EtOAc and water. The organic layer was dried and concentrated to produce a brown oil. The crude product was purified by MDAP to yield the formic acid salt. The salt was taken up in DCM and washed with sat. NaHCO3. The DCM layer was dried and concentrated to yield the title compound as a colourless oil (0.038 g). δH (CDCl3, 400 MHz) 8.02 (1H, d), 7.68 (1H, dd), 7.23 (2H, d), 7.15 (4H, m), 6.98 (2H, d), 6.78 (1H, d), 4.18 (1H, br.s), 3.80 (1H, d), 3.48 (3H, s), 3.46 (1H, d), 3.33 (1H, d), 3.08 (1H, td), 2.69 (1H, d), 2.51 (1H, d), 2.10 (1H, dd), 1.98 (1H, m), 1.46 (9H, s), 1.20 (3H, d). MS (ES): MH+ 535.3.
