Reaction Steps
A mixture containing 5-bromo-1,2,3,4-tetrahydroisoquinoline (212 mg, 1 mmol) and methylsulfonylethene (106 mg, 1 mmol) in dichloromethane is stirred at 35° C. for 14 hours. The solution is concentrated to afford 5-bromo-2-(2-(methylsulfonyl)ethyl)-1,2,3,4-tetrahydroisoquinoline as a brown oil (LC-MS m/z: 318.1 (M+1)) which is used without further purification in the next step.
