Reaction Steps
A solution of 2-chloropyridine-3-carboxaldehyde (3 g, 21 mmol), 4-(1-methyl-1H-benzo[d]imidazol-2-ylamino)phenol (5 g, 21 mmol), CESIUM CARBONATE (10 g, 32 mmol) in DMSO (60 mL) was heated to 80° C. overnight. Purification by aqueous workup (water, brine) and DCM extraction then Biotage (0-10% DCM/MeOH) produced product which partially solidified.
