We report on the covalent immobilization of the (S)-selective amine transaminase from Vibrio fluvialis (Vf-ATA) and its use in the synthesis of (S)-1-(5-fluoropyrimidin-2-yl)-ethanamine, a key intermediate of the JAK2 kinase inhibitor AZD1480. Immobilized Vf-ATA on glyoxyl-agarose (activity recovery: 30 %) was used in a packed-bed reactor to set-up a continuous flow biotransformation coupled with a straightforward in-line purification to circumvent the 2-step process described in literature for the batch reaction. The newly developed biotransformation was run in a homogeneous system including dimethyl carbonate as a green co-solvent. Optically pure (S)-1-(5-fluoropyrimidin-2-yl)-ethanamine (ee >99 %) was isolated in 35 % yield.

The myeloproliferative neoplasms, polycythemia vera, essential thrombocythemia, and idiopathic myelofibrosis are a heterogeneous but related group of hematological malignancies characterized by clonal expansion of one or more myeloid lineages. The discovery of the Jak2 V617F gain of function mutation highlighted Jak2 as a potential therapeutic target in the MPNs. Herein, we disclose the discovery of a series of pyrazol-3-yl pyrimidin-4-amines and the identification of 9e (AZD1480) as a potent Jak2 inhibitor. 9e inhibits signaling and proliferation of Jak2 V617F cell lines in vitro, demonstrates in vivo efficacy in a TEL-Jak2 model, has excellent physical properties and preclinical pharmacokinetics, and is currently being evaluated in Phase I clinical trials.
