Narrative:

On descent into ZZZ at approximately 21;000 while in moderate icing conditions (wing and cowls on); we received a wing anti-ice duct warning message. We ran the QRH which instructs to leave icing conditions. We contacted [ATC] and said we need a lower altitude to leave icing conditions. [After coordinating with ATC; we] received a descent to 11;000. At approximately 17;000; icing conditions were cleared. We elected to divert due to ZZZ1 entering indefinite holds. We landed without further incident.
