실험 절차

To a solution of the crude 4-nitrobenzenesulfonyl methylamide prepared above in 45 mL of ethanol, was added a 1 mL slurry of Raney Nickel. Hydrazine monohydrate (18 mmol) was added slowly in several portions. A change in the solution colour from yellow to colourless indicated the reaction was complete. The mixture was stirred for an additional 1 hr. The solids were removed by filtration and the solvent was evaporated. The resulting crude material was purified by flash column chromatography eluting with CH2Cl2:MeOH=10:1 to yield 2.09 g (90% for two steps) of the title compound as a pale orange powder.
