Versuchsvorschrift

To an acetic acid (5 mL) solution of 4-(2-furan-2-yl-ethyl)-benzaldehyde (480 mg, 2.4 mmol) described in Manufacturing Example 80-1-4 were added nitromethane (732 mg, 12 mmol) and ammonium acetate (370 mg, 4.8 mmol) under nitrogen atmosphere at room temperature, which was stirred for 2 hours at 120° C. The reaction mixture was partitioned into water and ethyl acetate. The organic layer was washed with water and saturated aqueous sodium chloride and dried over anhydrous magnesium sulfate, and the solvent was evaporated under a reduced pressure to obtain the title compound (554 mg, 95%) as a crude product.
