反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a solution of sodium hydride (60% in mineral oil, 90.24 mg, 2.25 mmol) in dry dimethyl formamide was added thiophenol (0.225 ml, 2.25 mmol) dropwise. To this was then added 5-Chloro-2-methoxy-N-methyl-benzenesulfonamide (531 mg, 2.25 mmol) followed by refluxing for 4 hours. The reaction mixture was cooled, diluted with ethyl acetate and washed with a 1N sulfuric acid solution. The organic layer was separated, dried over magnesium sulfate, filtered and concentrated in vacuo. Chromatography on silica gel yielded the above titled compound (320 mg, 53% yield). by refluxing for 4 hours The reaction mixture was cooled washed with a 1N sulfuric acid solution The organic layer was separated dried over magnesium sulfate filtered concentrated in vacuo

実験手順: To a solution of 5-Chloro-2-methoxy-benzenesulfonyl chloride (1.0 g, 4.15 mmol) in tetrahydrofuran(8 ml) was bubbled methylamine gas until saturated. The reaction mixture was sealed with a septa and stirred overnight at ambient temperature. The reaction mixture was then concentrated, triterated in dichloromethane and ether, filtered and dried yielding the above titled compound 1.05 g (>100%) white solid. The reaction mixture was sealed with a septa The reaction mixture was then concentrated ether, filtered dried
