Reaction Steps
A solution of fuming nitric acid (75 mL) was cooled to 10° C. followed by the addition of 5-chloro-thiophene-2-carboxylic acid ethyl ester (15 g, 78.7 mmol). The resulting mixture was stirred for 30 minutes at 10° C. followed by the addition of ice water. The solution was then extracted with ethyl acetate and dried, then concentrated under vacuum and purified by column chromatography using silica gel to provide 10.29 g (55%) of the title product.
