Procedure

A mixture of 4-benzylamino-benzaldehyde (5 g, 23.7 mmol) described in Manufacturing Example 68-1-1, nitromethane (2.55 mL, 47.7 mmol), ammonium acetate (2.74 g, 35.6 mmol) and acetic acid (50 mL) was stirred for 6 hours at 100° C. This mixture was cooled to room temperature, concentrated under a reduced pressure, and diluted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (5.82 g).
