2‐(methylamino)pyridinato titanium complex initially synthesized by Kempe is used as catalyst for efficient intramolecularhydroaminoalkylation reactions of secondaryaminoalkenes. The corresponding reactions of N‐aryl‐substituted 1‐aminohept‐6‐enes and 1‐aminohex‐5‐enes directly give access to 2‐methylcyclohexyl‐ or 2‐methylcyclopentylamines in good yields. In addition, intramolecularhydroaminoalkylations of an N‐alkyl‐substituted
