Reaction Steps

By the procedure of Example 11, p-methoxythiophenol (4.39 g., 31.4 mmoles) and cuprous oxide (2.25 g., 15.7 mmoles) heated at 135° C. for 2 hours were reacted with 5-bromofuran-3-carboxylic acid (3 g., 15.7 mmoles) in 60 ml. of dimethylformamide, and crude product (1.67 g. ) isolated. Recrystallization from methylene chloride/hexane gave purified 5-(4-methoxphenylthio)furan-3-carboxylic acid (825 mg., m.p. 115°-117° C., m/e 250).
