We show that dipyridylamine-acetamide (Dpaa), can be cleaved under mild acidic conditions (30% formic acid in dichloromethane). The release of the amine function is orthogonal to other acid-labileprotectinggroups. Calculations suggest that the ease of Dpaa cleavage relies on activation of the carbonyl function by the protonated dipyridylamine nitrogen and activation of a water molecule by a hydrogen-bond
