EXAMPLE 2 Preparation of 3-Amino-5,6-dibromopyrazinethiol Aminotribromopyrazine was prepared, by the same procedure reported for the trichloro analog, from tetrabromopyrazine. Using the same procedure as above, 30 g. of aminotribromopyrazine, and 24 g. of sodium sulfide nonohydrate in 500 IPA gave 13.5 g. (53% yield) of the desired compound. Anal. Calcd. for C4 H3 Br2 N3 S: C, 16.86; H, 1.06; N, 14.74. Found: C, 17.55; H, 1.21; N, 14.89.

General procedure: [0268] In a mixture of 3,5,6-tribromopyrazin-2-amine (146 mg, 0.5 mmol), triethylamine (202 mg, 2 mmol), and catalytic amount of DMAP (5 mol %) in dry CH2CI2 (5 mL) was added 3- fluorobenzoylchloride (176 mg, 1 mmol) at room temperature. The mixture was stirred at room temperature overnight, and concentrated under reduced pressure. The residue was then dissolved in MeOH (5 mL) and K2CO3 (100 mg) was added. The mixture was stirred at 60 C for 1 h. The mixture was then reduced down and the product purified via silica chromatography (ethyl acetate:hexanes).
