実験手順
To a solution of 1.0 g (6.13 mmol) of N-pyrazin-2-ylcyclopropanecarboxamide in 10 mL of dichloromethane at 0° C. was added a solution of 1.58 g (7.36 mmol) of O-mesitylenesulfonylhydroxylamine, prepared from mesitylenesulfonyl chloride using a procedure analogous to that described in the literature (Y. Tamura et al., J. Org. Chem., 38: 1239 (1973)). The reaction mixture was allowed to stir at ambient temperature for 1.5 h. The resultant thick yellow mixture was concentrated in vacuo to give the title compound as a yellow solid.
