2-Bromo-5-nitrothiazole → HCID 20333091, compound

Participants

Reaction Steps

To a solution of 4.36 (0.02 mol.) of 3,5-di(sodiomercapto)-4-isothiazole carbonitrile in methanol was added 8.4 g (0.04 mol.) of 2-bromo-5-nitrothiazole. A yellow-brown solid begins to precipitate almost immediately. The reaction mixture is stirred for an additional 2 hours at room temperature (~22° C.). The precipitate is collected by suction filtration, washed with water and methanol and dried in vacuo to yield 6.77 g (79% yield from the isothiazole) of a tan solid, m.p. 197°-199.5° C.
