Procedimiento

To a solution of anisole 2F (R=4-Methyl-3-pentenyl) (6 g) in dichloromethane (100 mL) and cooled in an ice bath is added a 1M solution of boron tribromide (3.4 mL). The solution is stirred for one hour, then poured into water. The reaction mixture is extracted with dichloromethane and dried over magnesium sulfate. The solution is concentrated in vacuo. The product is recrystallized from hexane.
