1-(3-bromopropyl)-4-ethenylbenzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The product from Example 2 is used as a stating material in this procedure. The resulting product from Example 2 was diluted in 200 mL of toluene. Next, 0.125 g of toluensulfonic acid was added to the reaction mixture. The reaction mixture was refluxed under argon atmosphere for 44 hours. The mixture was then washed with 50 mL of water and the solvent was removed under vacuum. The resulting product was then purified by silica gel chromatography with the use of 90% hexane and 10% ethyl acetate. The resulting product was recovered as the solvent was removed under vacuum.

Procedure: Also disclosed herein is a method of making 4-vinylbenzenepropanethiol. The method includes providing 1-bromo-3-phenylpropane, adding acetic anhydride and aluminum chloride, incubating the mixture at from about −20 to about 20 degrees Celsius for from about 1 hour to about 12 hours, isolating the resulting p-(3-bromopropyl)acetophenone, adding sodium borohydride to the p-(3-bromopropyl)acetophenone solution in methanol, incubating the mixture at about 0 degrees Celsius for about 2 hours, isolating the resulting p-(3-bromopropyl)-α-methylbenzenemethanol, adding toluensulfonic acid to the solution of p-(3-bromopropyl)-α-methylbenzenemethanol in toluene, refluxing the mixture under inert atmosphere for about 4 hours, isolating the resulting p-(3-Bromopropyl)styrene, adding thiourea to the p-(3-Bromopropyl)styrene, gently refluxing the mixture for about 16 hours, adding sodium hydroxide, and gently refluxing the mixture for about 4 hours. refluxing the mixture under inert atmosphere for about 4 hours
