Nitric Acid → HCID 18916400, compound

Participants

Reaction Steps

This compound was prepared in the manner of Step D, Example 6, with 8.0 grams (39 mmole) of 2,6-dichlorobenzothiazole, 45 mL of concentrated sulfuric acid, and 3.8 mL (60 mmole) of concentrated nitric acid as reagents. The material was purified by column chromatography on silica gel. Elution was accomplished with 3:1 heptane:ethyl acetate. The product-containing fractions were combined and concentrated under reduced pressure, yielding 2,6-dichloro-7 nitrobenzothiazole. The NMR spectrum was consistent with the proposed structure.
