2-[(4-fluorophenyl)methyl]morpholine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a tetrahydrofuran solution (4 mL) of 6-(4-fluorobenzyl)morpholin-3-one (100 mg, 0.48 mmol) synthesized in Reference Synthesis Example 43, lithium aluminum hydride (21.8 mg, 0.57 mmol) was added at 0° C. and the resultant solution was stirred for 4 hours. To the reaction solution, lithium aluminum hydride (20.0 mg) was added and the resultant mixture was stirred at room temperature for 1 hour. After completion of the reaction, saturated sodium sulfate aqueous solution was added to the reaction solution at 0° C. and the resultant mixture was stirred at room temperature for 20 minutes. The reaction solution was dried over added anhydrous magnesium sulfate and concentrated under reduced pressure to obtain a crude product (84.9 mg) of the title compound. was added at 0° C. was added to the reaction solution at 0° C. The reaction solution was dried over added anhydrous magnesium sulfate concentrated under reduced pressure
