The development and demonstration of a crystallization-induced dynamic resolution (CIDR) to prepare a chiral diarylmethylamine, a key intermediate toward the synthesis of a potent TRPM8 inhibitor, is described. Essential to the development of this process was the discovery of (1) efficient classical resolution conditions by a high-throughput screening method, (2) formaldehyde as the optimal racemization
