Next, to a solution of lithium aluminum hydride (204 mg, 5.39 mmol) in tetrahydrofuran (10 mL) was added a solution of the resulting 5-(3-bromophenoxy)-thiophene-2carbonitrile (1.01 g, 3.59 mmol) in tetrahydrofuran (10 mL), and the solution was stirred at room temperature for 2 hours. Then, lithium aluminum hydride (68 mg, 1.80 mmol) was added, and the solution was further stirred at room temperature for 1 hour. Water was added to the reaction solution, which was then extracted with ethyl acetate, dried over anhydrous magnesium sulfate, and the solvent was evaporated to obtain a mixture of the title compound and debrominated compound (740 mg) as a pale brown oil. As this mixture cannot be purified, it was used in the next reaction without purification.
