Reaction Steps

A solution of 2-(6-bromobenzothiazol-2-yl)-3-methoxybut-2-enenitrile (0.96 g, 3.1 mmol) and hydrazine hydrate (0.3 mL, 5.4 mmol) in methanol (30 mL) was heated to reflux overnight. The reaction was then cooled to room temperature. The resulting solid was isolated by filtration and was purified by flash chromatography to yield the title product. MS (m/z, ES+): 308.9 (Br79M+1, 100%), 310.9 (Br81M+1, 100%). Yield=5%.
