Reaction Steps

A solution of 4-(4-pyrrolidinophenyl)-1,2-naphthoquinone-2-oxime (0.005 mol) and 1-isobutyl-3,3-dimethyl-2-methyleneindoline (0.005 mol) in anhydrous ethanol (70 cm3) was refluxed until examination of the reaction mixture by thin layer chromatography indicated that none of the 4-(4-pyrrolidinophenyl)-1,2-naphthoquinone-2-oxime remained. The mixture was cooled, reduced in volume and the precipitated product collected by vacuum filtration washed with a little cold ethanol and dried. Yield=19%, m.p.=242-245° C., λmax=614 nm in PhMe upon irradiation.
