We extend a known method to integrate out the strange quark in three flavour chiral perturbation theory to the context of an arbitrary number of flavours. As an application, we present the explicit formulæ to one-loop accuracy for the heavy quark mass dependency of the low-energy constants after decreasing the number of flavours by one while integrating out the heaviest quark in N-flavour chiral perturbation theory.
