Abstract

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.
