Procedure

To a solution of 5-(4-hydroxy-3-methoxyphenyl)-penta-2,4-dienoic acid benzylamide (118 mg, 0.38 mmol) [Example 5] in 50 mL of dichloromethane, 100 μl of boron tribromide (0.95 mmol) was added dropwise at −78° C. The mixture was stirred for 15 min at −78° C. and for 1 h at room temperature. Water (100 ML) was added, the organic layer was separated, dried with Na2SO4 and evaporated.
