实验步骤: To a solution of anthranilonitrile (15.0 g) in diethyl ether (600 mL) was added a solution of 2.0 M cyclopentylmagnesium bromide in diethyl ether (159 mL) at 0° C. under nitrogen. The mixture was stirred at room temperature overnight (20 hours). 500 ml of 5 N HCl in H2O was added very slowly at 0° C. The mixture was stirred at room temperature for 1 hour. The aqueous layer was neutralized with 50% NaOH/H2O to pH=12. 2×500 mL of ethyl acetate was used to extract the aqueous layer. The combined organic layers were dried over Na2SO4. The solvent was removed to give the crude product 22.5 g (93.6% yield). H1NMR(CDCl3): δ6.62-7.82 (m, 4H), 3.64-3.78 (m, 1H), 1.50-1.96 (m, 8H). The mixture was stirred at room temperature for 1 hour to extract the aqueous layer The combined organic layers were dried over Na2SO4 The solvent was removed

实验步骤: To a stirred solution of phenyl-carbamic acid tert-butyl ester (1.2 g, 6.2 mmol) in Et2O (12 mL) under a nitrogen atmosphere was added dropwise a 1.7 M solution of t-BuLi in pentan (8.4 mL, 14.3 mmol) over a 10-min period at −20° C. The mixture was stirred at −10° C. for 2.5 h and then cyclopentanecarboxylic acid methoxy-methyl-amide (1.07 g, 6.8 mmol) was added over 5 min. The mixture was allowed to warm to room temperature and stirred for further 1 h before it was quenched with aqueous NH4Cl. The organic phase was isolated and the aqueous phase was extracted with CH2Cl2, and the combined organic phases were dried and concentrated in vacuo. The crude material was dissolved CH2Cl2 (18 mL) and TFA (6 mL) and stirred at room temperature for 2 h. The reaction mixture was evaporated in vacuo, and added aqueous NaHCO3 to pH 7 and extracted with CH2Cl2. The combined organic phases were dried and concentrated in vacuo to give 1.03 g (68%) of (2-amino-phenyl)-cyclopentyl-methanone as an oil. to warm to room temperature stirred for further 1 h before it was quenched with aqueous NH4Cl The organic phase was isolated the aqueous phase was extracted with CH2Cl2 the combined organic phases were dried concentrated in vacuo The crude material was dissolved CH2Cl2 (18 mL) and TFA (6 mL) stirred at room temperature for 2 h The reaction mixture was evaporated in vacuo added aqueous NaHCO3 to pH 7 extracted with CH2Cl2 The combined organic phases were dried concentrated in vacuo
