実験手順

To a solution of 2-(3-methoxy-1-propynyl)pyridine (13.2 g) dissolved in dichloromethane (50 mL) was added a solution of O-mesitylenesulfonylhydroxylamine (Reference; Synthesis, 1997, 1) (21 g) in dichloromethane (80 mL) dropwise while cooling with ice, and the reaction mixture was stirred for 30 minutes. Diethyl ether (1 L) was added to the obtained reaction mixture to precipitate crystals, which were collected by filtration and dried under reduced pressure to afford a crude product of 1-amino-2-(3-methoxy-1-propynyl)pyridinium 2,4,6-trimethyl-1-benzenesulfonate as ecru crystals (27.1 g).
