反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:-10.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a 3-necked 2-L flask was added N-benzyl-N-methylethanolamine (30.5 g, 0.182 mol), DCM (0.5 L), DIPEA (95 mL, 0.546 mol) and DMSO (41 mL, 0.728 mol). Using an ice bath, the mixture was cooled to about −10° C. and sulfur trioxide pyridine-complex (87 g, 0.546 mol) was added in 4 portions over 5 minute intervals. The reaction was stirred at −10° C. for 2 hours. Before removing the ice-bath, the reaction was quenched by adding water (0.5 L). The aqueous layer was separated and the organic layer was washed with water (0.5 L) and brine (0.5 L) and then dried over magnesium sulfate and filtered to provide the title compound which was used without further purification. Before removing the ice-bath the reaction was quenched by adding water (0.5 L) The aqueous layer was separated the organic layer was washed with water (0.5 L) and brine (0.5 L) dried over magnesium sulfate filtered
