synthesis amenable to produce multikilogram amounts of PI3K/mTOR inhibitor GDC-0980. The route employed metalation/formylation and reductive amination followed by a metal catalyzed Suzuki–Miyaura cross-coupling. The metalation was performed via triarylmagnesiate intermediates allowing formylation under noncryogenic conditions. 2-Picoline·BH3 was employed to replace Na(OAc)3BH in the reductive amination and
