实验步骤: The product from Example 297A (4.00 g, 19.4 mmol) in acetone (9 mL) at 0° C. was treated with sodium azide (1.27 g) in water (9 mL) dropwise over 15 minutes. after stirring for 30 minutes at 0° C., the mixture was extracted with toluene (20 mL). The toluene solution was dried over MgSO4, filtered, and the filtrate was heated to reflux for 1 hour. The cooled solution was concentrated under reduced pressure to provide the title compound. the mixture was extracted with toluene (20 mL) The toluene solution was dried over MgSO4 filtered the filtrate was heated to reflux for 1 hour The cooled solution was concentrated under reduced pressure

实验步骤: 2-(4-Chlorophenyl)-2-methylpropanoic acid (3.85 g, 19.4 mmol) in toluene (5 mL) and thionyl chloride (5.00 g, 3.1 mL) was heated at 80° C. for 2 hours. The mixture was cooled and concentrated under reduced pressure to provide the title compound. The mixture was cooled concentrated under reduced pressure

实验步骤: The product of Example 76A (4.00 g, 19.4 mmol) in acetone (9 mL) at 0° C. was treated with a solution of sodium azide (1.27 g) in water (9 mL) dropwise over 15 minutes. After stirring for 30 minutes at 0° C., the mixture was extracted with toluene (20 mL). The organic extract was dried with MgSO4, filtered, and the filtrate heated at reflux for 1 hour. The mixture was allowed to cool to room temperature and was concentrated under reduced pressure to provide the title compound as a pale yellow oil (3.45 g, 96%). the mixture was extracted with toluene (20 mL) The organic extract was dried with MgSO4 filtered the filtrate heated at reflux for 1 hour to cool to room temperature was concentrated under reduced pressure

实验步骤: 2-(4-Chlorophenyl)-2-methylpropanoic acid (3.85 g, 19.4 mmol) in toluene (5 mL) was treated with thionyl chloride (5.00 g, 3.1 mL) and heated at 80° C. for 2 hours. The cooled solution was concentrated under reduced pressure to provide a yellow oil containing a crystalline residue. The mixture was dissolved in hexane, filtered and the filtrate concentrated to provide the compound as a pale yellow oil (4.10 g, 98%). The cooled solution was concentrated under reduced pressure to provide a yellow oil containing a crystalline residue filtered the filtrate concentrated

实验步骤: 2-(4-chlorophenyl)-2-methyl propionyl chloride was prepared as follows: To a flask containing 2-(4-chlorophenyl)-2-methyl propionic acid (15.0 g, 75.6 mmol) was added thionyl chloride (approx. 6 mL). Dichloromethane (20 mL) was then added before adding an additional portion of thionyl chloride (approx. 12 mL). The reaction was allowed to heat to 40° C. for two hours before cooling to room temperature and concentrating in vacuo (azeotroping with tetrahydrofuran). The resulting acid chloride was used in the following acylation step without further purification or characterization. before cooling to room temperature concentrating in vacuo (azeotroping with tetrahydrofuran) The resulting acid chloride was used in the following acylation step without further purification or characterization
