To an acetic acid (1.5 mL) and dimethyl sulfoxide (26 mL) solution of (4-((E)-2-nitro-vinyl)-benzyl)-phenyl-amine (1.53 g, 6.02 mmol) described in Manufacturing Example 73-1-4 was added sodium borohydride (364 mg, 9.63 mmol) at room temperature while cooling appropriately. This mixture was stirred for 1.5 hours at room temperature. This mixture was partitioned into ethyl acetate and water. 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 (1.5 g). This compound was used in the subsequent reaction without being purified.
