S-[(4-bromophenyl)methyl] ethanethioate

Conditions: temp:15.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of N-chlorosuccinimide (3.95 g, 29.6 mmol) in acetonitrile (11.6 mL) and 1 M HCl (2.31 mL) at 0° C. was slowly added a solution of thioacetic acid S-(4-bromo-benzyl)ester (1.81 g, 7.39 mmol) in acetonitrile (6.3 mL) over 60 minutes whilst allowing the reaction to warm to 15° C. The remaining solution was added and reaction left to warm to room temperature for 10 minutes. The mixture was cooled to 0° C. and stirred for 1 hour. Water was added and the product was extracted with EtOAc, washed with brine, dried with Na2SO4, concentrated to give (4-bromo-phenyl)-methanesulfonyl chloride (2.6 g, 9.6 mmol). 1H NMR (300 MHz, CDCl3): δ 7.60 (d, 2H), 7.36 (d, 2H), 4.81 (s, 2H). the reaction The remaining solution was added reaction left to warm to room temperature for 10 minutes The mixture was cooled to 0° C. the product was extracted with EtOAc washed with brine dried with Na2SO4 concentrated

Conditions: temp:15.01; pressure:0.00; stir:; See reaction.notes.procedure_details.
