Reaction Conditions

Reaction Steps

A mixture of 3,6-dimethylpyrazin-2-amine (1.23 g, 10 mmol) in DCM (20 mL) was cooled to 0° C. and a solution of O-(mesitylsulfonyl)hydroxylamine (4.3 g, 20 mmol) was added slowly. The reaction mixture was allowed to warm to room temperature for 3 h and filtered. The solid collected was washed with DCM (50 mL) to give 1-amino-3,6-dimethylpyrazin-2(1H)-iminium-2,4,6-trimethylbenzenesulfonate as a brown solid (2.0 g, yield 59%). ESI MS: m/z 139 [M−199]+.
