A silver-loaded titanium dioxide (Ag/TiO2) photocatalyst enables a facile N-methylation of amines with methanol at room temperature under UV-vis light irradiation. This method tolerates various functional groups including N-benzyl, N-allyl, N-Boc, hydroxyl, ether, acetal, carboxamide, formamide, and olefin groups.
