Participants

Reaction Steps

The base of compound (48) was reacted with 1-bromo-3-methyl-sulphanyl-benzene corresponding to the conditions described in Example 1. In departure from the conditions described in Example 1, ether was used as the solvent and 1,2-dibromoethane was added to the reaction batch in order to increase the yield. The crude product was purified with diisopropyl ether via a silica gel column and was taken up in 2-butanone. After the addition of trimethylchlorosilane/water, compound (51) was obtained in a yield of 23% theoretical.
