Reaction Steps

To a suspension of 3-chloro-5-methoxybenzo[b]thiophene-2-carbonyl chloride (1.52 g, 5.82 mmol) [Connor D. T., et al., J. Med. Chem. 35, 935 (1992)] in 80 mL of toluene at 50° C. is added dropwise 10 mL of aqueous NH4OH. The resulting precipitate is collected by filtration and recrystallized from methanol to provide 3-chloro-5-methoxybenzo[b]thiophene2-carboxamide; mp=220°-222° C.
