To a suspension of lithium aluminum hydride (1.95 g, 51.3 mmol) in tetrahydrofuran (50 mL) was added dropwise a tetrahydrofuran solution of 4-phenylsulfanylmethyl-benzoic acid (5 g, 20.5 mmol) described in Manufacturing Example 206-1-1, which was stirred for 30 minutes at room temperature. This mixture was cooled with ice water, and water was carefully added. The mixture was filtered through a Celite bed, and the filtrate was combined. The organic layer was separated, washed with water, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (2.01 g). The title compound was used in the following reaction without any further purification.
