Reaction Steps

In analogy to example 11.9, trans-[4-(4-Bromo-butoxy)-cyclohexyl]-methyl-amine hydrochloride and 3,4-difluoro-benzenesulfonyl chloride (with 2.1 eq N,N-diisopropylethylamine) were reacted to yield trans-N-[4-(4-Bromo-butoxy)-cyclohexyl]-3,4-difluoro-N-methyl-benzenesulfonamide which was used directly in the next steps see Example 12.55-12.56 and 12.65 and 12.66.
