Having established suitable conditions for the photocatalytic event, we turned our attention to optimize the ensuing fragmentation of intermediate 2a, which would ultimately yield the targeted cross-coupled product 3. A one-pot, two-step protocol was developed, in which direct addition of 3 equivalents of triethylamine and heating the reaction mixture to 80 °C afforded 3 in good isolated yield (Table , Entry 1). Control experiments revealed that both the presence of a base and the supply of thermal energy were crucial (Table , Entries 2-4).
