Procedure

1.38 g of (Z)-3-(3-nitro-4-methylphenyl)-2-(3,4,5-trimethoxyphenyl)-prop-2-ene-nitrile was dissolved in 500 ml of acetone and the mixture was reacted in a photochemical apparatus (visible light) for 1 hour. The reaction mixture was concentrated and a quarter of it was purified on a silica gel plate to give 100 mg of the intended compound.
