Procedure

1-(4-Carbomethoxyphenyl)-2-nitroprop-1-ene (31.0 g) in tetrahydrofuran (900 ml) was stirred with aluminium amalgam, made in the usual way from aluminium (13.5 g) and mercuric chloride (6.9 g). The mixture was cooled in ice and stirring was continued until reaction was complete. The slurry was filtered through celite and the filtrate was evaporated to give a cream solid (17.0 g). τ (CDCl3) 8.27 (3H, s), 6.22 (2H, s), 6.13 (3H, s), 2.63 (2H, d, J=8 Hz), 1.95 (2H, d, J=8 Hz).
