(R)‐1‐(4‐chloro‐2‐(3‐methyl‐1H‐pyrazol‐1‐yl)phenyl)‐2,2,2‐trifluoroethan‐1‐ol [(R)‐2] is a key chiral intermediate in the synthesis of telotristat ethyl, an anti‐carcinoid syndrome drug. However, the synthetic methods for (R)‐2 mainly include chemical reductions, rarely involving biocatalysis or bioreduction until now. Here, we report a method for obtaining (R)‐2 by biocatalytic reduction of corresponding
