반응 단계

A solution of 15.05 g (78.3 mmol) of the product of Step A in 25 mL of 1,2-dichlorobenzene was magnetically stirred and refluxed (183° C.) under an argon atmosphere for 18 hours. At this point, the reaction mixture was cooled to room temperature and applied to a 6 cm diameter by 18 cm silica gel flash chromatography column and eluted with 25% ethyl acetate-hexane to separate the 1,2-dichlorobenzene, then with 40% ethyl acetate-hexane to elute the product. The product fractions were concentrated in vacuo and the residual oil was crystallized from hexane to afford 13.70 g (91%) of the title compound.
