Other workers have reported that tertiary aliphatic amines undergo a decomposition reaction with sulfonyl chlorides (8) and therefore would be unsatisfactory acid acceptors for these reactions. We have found no evidence that such a reaction occurs at any temperature in our system, and in fact aliphatic tertiary amines are excellent acid acceptors for such condensations. 

Reaction with sulfonyl chlorides to give sulfonamides (Section 19-13)... 

AT-substituted benzimidazoles 62 and 63 (Fig. 6) have been reported to show anti-hepatitis B virus activity, and thus several derivatives of novel benzimidazoles 62 and 63 have been prepared by Li et al. [53]. The precursor benzimidazoles readily undergo AT-substitution reactions with sulfonyl chlorides in dichloromethane using DMAP as a base, whereas methylation can...
