The present disclosure relates to compounds of formula (Ia) and pharmaceutically acceptable salts thereof, pharmaceutical compositions comprising the same, methods of preparing the same, intermediate compounds useful for preparing the same, and methods for treating or prophylaxis of diseases, in particular cancer or conditions with dysregulated immune responses or other disorders associated with aberrant AHR signaling. These compounds may also be useful in treating cancer when administered in combination with at least one additional therapy.
Problem solved: an air-stable 2-pyridyl borane that can effectively couple to a wide range of aryl and heteroaryl halides and pseudohalides has evaded the synthesis community for decades. The discovery that Cu(DEA)(2) powerfully enables palladium-mediated cross-couplings with air-stable boronates 1 has finally provided a general solution to this problem. DEA=diethanolamine, DMF=N,N'-dimethylformamide, Tf=trifluoromethanesulfonyl.

A wide range of 2-pyridyl and other difficult-to-access heterocyclic N-methyliminodiacetic acidboronates can be readily prepared from the corresponding bromides via a new method involving direct transligation of 2-heterocyclic trialkoxyborate salts with N-methyliminodiacetic acid (MIDA) at elevated temperatures.
