A practical and chromatography-free multikilogram synthesis of a 3-isoxazolol containing antifibrinolytic agent, AZD6564, has been developed in eight steps and 7% overall yield starting from methyl 2-chloroisonicotinate. Highlights in the synthesis are a Negishi coupling and an enzymatic resolution of a racemic ester.
