3-Methyl-4-anisaldehyde → 1-Methoxy-2-methyl-4-[2-(4-nitrophenyl)ethenyl]benzene

Participants

Reaction Steps

Sodium ethoxide (prepared from 0.70 g of Na and 30 mL of ethanol) was added to an ice-cold mixture of diethyl p-nitrobenzylphosphonate (9.09 g, 0.033 mole) and 3-methyl-p-anisaldehyde (5.0 g, 0.033 mole) in ethanol (about 100 mL). The resulting mixture was stirred overnight. The solid product was filtered, washed with ethanol and vacuum dried to give MMONS, 3-methyl-4-methoxy-4'-nitrostilbene (4.946 g, 0.0157 mole, 47.6% yield, m.p. 109°-111° C.). Recrystallization of MMONS from chloroform/ethanol gave crystals suitable for x-ray analysis.
