Reaction Conditions

Reaction Steps

This compound was prepared in a manner analogous to that set forth in Step C of Example 2, using 0.65 gram (0.0045 mole) of 2-chloro-3-nitropyrrole (prepared in Steps D-F of Example 1) and 5.0 mL (excess) of dimethylamine. The microwave chemical reactor was maintained at 100° C. during a 45-minute period, after which time the reaction was considered to be complete. The crude product was purified with column chromatography on silica gel. Elution was accomplished using 25% hexane in diethyl ether, then 100% diethyl ether as eluants. The appropriate fractions were combined and concentrated under reduced pressure, yielding 0.2 gram of the subject compound. The NMR spectrum was consistent with the proposed structure.
