Procedure

A mixture of sodium methylate in methanol (5.4 mol/l, 19.6 mmol), 2,6-dichloro-3',4'-dimethoxy-6'-methyl-2'-pentyloxy-benzophenone (obtained according to EP 0 727 141, 2.69 g, 6.5 mmol) and dimethoxyethane (20 ml) is heated to 80° C. with stirring for 24 hours. A mixture of water and ethyl acetate (1:1 v/v; 100 ml) is then slowly added at room temperature. The organic phase is separated and concentrated and the residue is purified by column chromatography (dichloromethane) yielding the pure product as a yellow oil, 0.52 g, (19.7%).
