This work reports a mild and efficient approach for the synthesis of substituted quinazolines using 1‐(2‐aminoaryl)ethan‐1‐ones in conjunction with arylmethanamines as starting materials via visible‐light‐induced benzylic C–H functionalization. The reaction proceeded at room temperature with low catalyst loading and the reaction system was clean from beginning to end. Significantly, this method exhibited good tolerance even to free hydroxyl group and amino group contained in substrates.
