Participants

Reaction Steps

N-(dibenzo[b,d]thiophen-4-yl)-N-(4-methoxyphenyl)dibenzo[b,d]thiophen-4-amine (4.6 g, 9.4 mmol) was dissolved in 100 mL of anhydrous dichloromethane. The solution was cooled with a dry ice/isopropanol bath. To the solution was added boron tribromide solution in hexanes (1.0 M solution, 16 mL). The reaction was allowed to warm to room temperature for 6 h. The reaction was quenched with water. The product was purified with column chromatography using dichloromethane as eluent. 4 g of desired product was obtained. (90% yield)
