The first example of mono Suzuki-Miyaura cross-coupling of N-Boc-2,5-dibromopyrrole with a boronic acid (indol-2-ylboronic acid) is reported. The resulting 2-indolyl-5-bromopyrrole derivative was in turn coupled with a variety of aryl- or heteroarylboronicacids thereby providing the corresponding non-symmetrical 2,5-disubstituted pyrroles in good to excellent yields. The tert-butoxycarbonyl (Boc)
