Reaction Steps

6-(2-Imidazole-1-yl-ethoxy)-3,4-dihydro-2H-naphthalen-1-one (0.200 g, 0.78 mmol) was reacted with 5-nitrothiophene-2-carboxaldehyde (0.123 g, 0.78 mmol) in a mixture of HOAc (1 mL) and concentrated H2SO4 (0.100 mL) at room temperature overnight. The reaction was diluted with water, and the resulting precipitate was collected, washed well with water, and dried in vacuo at 60° C. to afford 0.296 g (80%) of the title compound as a brown powder, mp >240° C.: APCI-MS m/e 396.1 (M+ +1).
