A solution of 103 mg (0.381 mmol) of 4-[2-(morpholine-4-sulfonyl)-ethyl]-phenylamine (as prepared in the previous step) in CH2Cl2 (15 mL) was cooled to 0° C. and treated portionwise with 67.8 mg (0.381 mmol) of solid NBS. The mixture was stirred at 0° C. for 15 min, diluted with CH2Cl2 (30 mL) and washed with saturated aqueous NaHCO3 (1×20 mL). The organic layers were dried (MgSO4) and concentrated in vacuo to afford 133 mg (100%) of the title compound as a tan solid: Mass spectrum (ESI, m/z): Calcd. for C12H17N2O3SBr, 349.0/351.0 (M+H). found 348.7/350.8.
