A practical Brønsted acid promoted benzylicC–Hfunctionalization of 2-methylazaarenes and nucleophilic addition to aldehydes was developed in good to excellent yields. A six-membered hydrogen-bonding transition state is proposed to be crucial for the reaction. Ready availability of the two starting materials, the use of acetic acid as the catalyst and the facile reaction conditions will guarantee
