Procedure
A mixture of N-(3-(thiophen-2-ylthio)propyl)acetamide (2.5 g, 11.6 mmol, 1.0 eq), NBS (2.1 g, 11.6 mmol, 1.0 eq) in DMF (5 mL) was stirred at 23° C. for 1 hour. The mixture was extracted with CH2Cl2. The combined organic layers were dried (Na2SO4), filtered and concentrated to give yellow oil N-(3-(5-bromothiophen-2-ylthio)propyl)acetamide (1.6 g, 46.8%);
