strategy involves oxidative coupling of aryl methyl ketones and 2‐aminopyridines in the presence of DMF. The reaction does not require pre‐functionalization of the substrates, thus making it a practically applicable approach for the generation of β‐amino ketones. The reaction requires the use of tin(II) chloride dihydrate (SnCl2⋅2 H2O) as Lewis acid in the presence of tert‐butyl hydroperoxide (TBHP) as the
