Versuchsvorschrift
The title compound was prepared as described in Taylor, W P, et. Al, Bioorg. Med. Chem. 4:1515-1520 (1996). 4-Nitrobenzaldehyde (3.0 g, 19.85 mmol) and diethyl phosphonate (2.74 g, 19.85 mmol) were combined and treated with a 0.5N solution of sodium methoxide in methanol (0.993 mL, 0.496 mmol). The resulting red-orange solution was stirred 12 h at room temperature. The reaction mixture was extracted with dichloromethane (20 mL) followed by half saturated ammonium chloride (20 mL). The organic layer was separated, dried and concentrated under vacuum to provide the title compound as a semi-solid (5.1 g, 89%).
