Procedure
tert-butyl methylcarbamate (prepared following a method substantially similar to the one described in JACS, 2003, 125, 7307-7312)(10.52 g, 80.21 mmol, 1.05 eq.) was dissolved in dry THF (120 mL) and cooled in an ice-bath. NaH (3.51 g, 87.84 mmol, 60%, 1.15 eq.) was added portionwise and the resultant suspension was stirred at RT for 1 hour. The suspension was cooled in an ice-bath and 2,6-dicloropyrazine (11.38 g, 76.39 mmol, 1 eq.) was added portionwise. The reaction mixture was stirred at RT overnight.
