Reaction Steps
NaH (60%, 20 mg) was added into a solution of 2-amino-5-(tri-n-butylstannyl)pyrazine (0.2 g) in THF (30 mL) at room temperature. After the mixture stirred at room temperature for 30 minutes, to it was added methylsulfonyl chloride (63 mg). The reaction mixture was stirred at room temperature over 8 hours. The reaction was quenched with aqueous ammonium chloride solution. The organic layer was separated, and the aqueous layer was extracted with ethyl acetate (3×100 mL). The combined organic extract was dried over magnesium sulfate, filtered and the filtrate was concentrated in vacuo. The residue was purified by silica gel chromatography to afford 2-methylsulfonylamino-5-(tri-n-butylstannyl)pyrazine (20 mg).
