Procedure

According to general procedure C, 4-Bromobenzene sulfonyl chloride (0.40 g, 1.56 mmol) and morpholine (0.34 mL, 3.90 mmol) were stirred together in dry dichloromethane (5 mL) for 16 hours. 4-[(4-bromophenyl)sulfonyl]morpholine (0.13 g, 28%) was provided after purification. MS (ESI) m/z 306. HPLC purity 100.0% at 210-370 nm, 8.2 min.; the Xterra® RP18 column, 3.5μ, 150×4.6 mm column, 1.2 mL/min., 85/15-5/95 (ammonium formate buffer pH=3.5/ACN+MeOH) for 10 min., hold 4 min.
