실험 절차
Compound 39 (8.47 g) was divided into eight portions (1.06 g each). Then, P(OEt)3 (per 7 mL) was added to each portion. The resulting mixtures were subjected to argon blow, heated to 90° C., kept at this temperature for 3 days, cooled, and diluted with ether. The precipitate obtained was filtered and washed with CH2Cl2. Yield of carbazole 40: 3.33 g.
