Procedure
Following the procedure of Example 9, except that a total volume of 90 ml. of dimethylformamide was used, 1-thionaphthol (5.02 g., 31.4 mmoles) was reacted with 5-bromofuran-3-carboxylic acid. Crude product was isolated as an oil according to Example 16. The oil was solidified by trituration with water (988 mg.). Recrystallization from hexane gave purified 5-(1-naphthylthio)furan-3-carboxylic acid (250 mg., m.p. 118°-120° C., m/e 270).
