Procedure

A mixture of 2,6-dichloropyrazine (2.99 g), 1-cyclopropylmethanamine (2.14 g), potassium carbonate (4.14 g) and DMA (20 ml) was stirred at 80° C. for 23 hr. Water (15 mL) was added, and the mixture was extracted with ethyl acetate. The aqueous layer was extracted again with ethyl acetate. The combined organic layer was washed with water and saturated brine, dried over magnesium sulfate, and concentrated. This was used without purification for the next reaction.
