The next step towards the target NInC heterodimers, namely, borylation of the thus obtained iodo-InC 7 was also unsuccessful using the standard Miyaura borylation 25 conditions; however, in an innovative fashion, combining the Buchwald amination reaction conditions and catalyst with that of Miyaura borylation furnished the desired boronate ester 8 in acceptable yields i.e. ~ 30% (Scheme 2), but excellent purity as evidenced by H NMR (ESI S47 †).
