Procedure

A mixture of 3,N,N-trimethyl-4-vinyl-benzamide (706 mg, 3.73 mmol), triphenylsilanethiol (1.76 g, 6.00 mmol) and AIBN (185 mg, 1.13 mmol) in toluene (16 ml) was heated with stirring at 88° C. for two hours in a sealed test tube in an N2 atmosphere. The reaction mixture was cooled to room temperature and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane/ethyl acetate=2/1) to give 3,N,N-trimethyl-4-(2-triphenylsilanylsulfanyl-ethyl)-benzamide (1.24 g, 69%).
