Reaction Steps
To a stirred solution of the above benzonitrile intermediate (7.5 g, 34.4 mmol) in dry THF (50 mL) at 0° C. was added a mixture of sodium bis(trimethylsilyl)amide (1.0 M, 34 mL, 34 mmol) and cyclopentanemethanol (3.4 g, 34 mmol) in THF (100 mL). The reaction was allowed to warm up to room temperature and stirred overnight. Water (50 mL) was added to the reaction and the product was extracted by CH2Cl2 (2×50 mL). The solvent was washed with brine and dried over Na2SO4. The solvent was removed to give 4-bromo-2-cyclopentylmethoxy-6-fluorobenzonitrile (4.5 g, 43.9%).
