Participants

Reaction Steps

A solution of 7.9 g. of crude 3-chlorocarbonyldibenzothiophene in 700 ml. of ether was added with stirring to a solution of 2.7 g. of diazomethane in 180 ml. of ether in an ice bath. The solution was stirred for 7 hours and then the solvent was removed, on a steam bath, to yield the crude 3-diazomethylcarbonyldibenzothiophene (7.5 g.) which was used directly in the next step.
