实验步骤: Prepared according to the procedure described in Example 1, Step 4, using the following starting materials: ethyl-[2-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-5-trifluoromethyl-benzyl]-carbamic acid benzyl ester and (5-bromo-2-fluoro-phenyl)-acetic acid methyl ester. Prepared

反应条件: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of (5-bromo-2-fluoro-phenyl)-acetic acid (2.3 mmol) in MeOH (15 mL) was added 4N HCl in 1,4-dioxane (2 mL), and the reaction was stirred at 90° C. for 2 hours. The mixture was concentrated, and the residue was purified by silica gel chromatography to give the title compound. The mixture was concentrated the residue was purified by silica gel chromatography

反应条件: temp:64.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 5-bromo-2-fluorophenylacetic acid (5 g) in MeOH (200 mL) is added concentrated sulfuric acid (2 mL) and the solution is heated at 64° C. for 16 hours. The solution is evaporated in vacuo and the residue is taken up in EtOAc and washed with 10% sodium bicarbonate, brine and dried over sodium sulfate. The solution is filtered and evaporated in vacuo to afford (5-bromo-2-fluoro-phenyl)-acetic acid methyl ester (5.1 g). 1H NMR (300 MHz, CDCl3) □7.3-7.5 (m, 2H); 6.9 (m, 1H); 3.9 (s, 3H). The solution is evaporated in vacuo washed with 10% sodium bicarbonate, brine dried over sodium sulfate The solution is filtered evaporated in vacuo
