To a solution of titanium(IV) chloride (11.6 g) in dichloromethane (100 ml) was added 4-n-Pentyloxyacetophenone (10.3 g) and Methyl 4-formylbenzoate (8.21 g) in dichloromethane (50 ml) dropwise at 0° C. To the mixture was added triethylamine (11.15 ml) in dichloromethane (30 ml). The mixture was stirred at 0° C. for 30 minutes and diluted with n-hexane. The organic layer was washed with water (four times), brine and dried over magnesium sulfate. The solvents were removed under reduced pressure and the residue was triturated with iso-propyl ether. The solid was collected by filtration and dried to give 1-(4-Methoxycarbonylphenyl)-3-(4-n-pentyloxyphenyl)-1-propen-3-one (4.02 g).
