Resumo

Reaction of trifluoromethanesulfonamide with 2-methyl-1-pentene in the presence of N -bromosuccinimide in acetonitrile leads to N -{2-methyl-1-[(trifluoromethyl)sulfonamido]pentan-2-yl}acetamide. Cyclization of N -[1-phenyl-2-(triflamido)ethyl]acetamide with excess K2CO3 gives the corresponding 4,5-dihydro-1 H imidazole.
