Benzotriazole adducts methoxycarbonylamino‐1‐(1‐benzotriazolyl)alkanes 1 were derived from the condensation of an aldehyde, benzotriazole, and methylcarbamate. The leaving tendency of methoxycarbonylamino group (MeOCONH) and benzotriazole group (Bt) was investigated by treatment of the adducts with activemethylenecompounds under either Lewis acid‐catalyzed or basic conditions. In the presence of
