Procedure

7-Acetamido-3,4-epoxy-3,4-dihydro-2,2-dimethyl-6-nitro-2H-benzo[b]pyran (0.76 g,) was dissolved in dry ethanol and saturated with dry ammonia, and stirred at room temperature for 21 hr. Evaporation gave a crude mixture which was purified on the chromatotron (using pentane-ethyl acetate in a gradient elution), to give the title compound (280 mg).
