Procedure

To a suspension of 4-acetylbenzenesulfonyl chloride (5.5 g, 25 mmol) in CH2Cl2 (75 mL) and Et3N (2 equiv, 7.0 mL, 50 mmol) was added morpholine (1.5 equiv, 3.3 mL, 38 mmol) dropwise. The mixture was stirred at room temperature for 30 min. The mixture was then diluted with CH2Cl2 (100 mL) and washed with 5% HCl (2×50 mL), water (50 mL), and then brine (50 mL). The organic layer was dried (Na2SO4), filtered, and concentrated to afford crude 1-[4-(morpholine-4-sulfonyl)phenyl]ethanone (2) (4.78 g, 18 mmol, 71%): HPLC Retention Time; 5.82 min. (Method B) M+1, 270.0.
