A concise route to 3‐aryl‐1‐trifluoromethyltetrahydroisoquinolines by a benzylic [1,5]‐hydride shift‐mediated CH bond functionalization was developed. The [1,5]‐hydride shift of the benzylic C(sp3)H bond to the trifluoromethylketimine derived from para‐anisidine occurred smoothly to produce cis‐1‐trifluoromethyl‐3‐aryltetrahydroisoquinolines in good to excellent chemical yields with good diastereoselectivities
