Procedure

A solution prepared from 1,2-dichlorobenzene (65 mL) and the product of Step F (3.226 grams) was refluxed for 8 hours. The reaction, cooled to approx. 50° C., was subjected to high vacuum, removing the solvent by distillation. The remaining solid was digested in refluxing cyclohexane, cooled to ambient and filtered. The mother liquor was evaporated and chromatographed over silica gel (2.5:1 hex/ethyl acetate), producing more solid which was added to the previous, providing all the available title compound.
