Herein, we report the synthesis of carbon-13 and carbon-14 labeled empagliflozin. Carbon-13 labeled empagliflozin was prepared in five steps and in 34% overall chemical yield starting from the commercially available a-D-glucose-[13C6]. For the radiosynthesis, the carbon-14 atom was introduced in three different positions of the molecule. In the first synthesis, Carbon-14 D-(+)-gluconic acid delta-lactone was used to prepare specifically labeled empagliflozin in carbon-1 of the sugar moiety in four steps and in 19% overall radiochemical yield. Carbon-14 labeled empagliflozin with the radioactive atom in the benzylic position was obtained in eight steps and in 7% overall radiochemical yield. In the last synthesis carbon-14 uniformly labeled phenolwas used to give [14C]empagliflozin in eight steps and in 18% overall radiochemical yield. In all these radiosyntheses, the specific activities of the final compounds were higher than 53 mCi/mmol, and the radiochemical purities were above 98.5%.

An efficient production synthesis of the SGLT-2 inhibitor Empagliflozin (5) from acid 1 is described. The key tactical stage involves I/Mg exchange of aryl iodide 2 followed by addition to glucono lactone 3 in THF. Subsequent in situ treatment of the resulting lactol with HCl in MeOH produces beta-anomeric methyl glycopyranoside 4 which is, without isolation, directly reduced with Et3SiH mediated by AlCl3 as a Lewis acid in CH 2Cl2/MeCN to afford 5 in 50% overall yield. The process was implemented for production on a metric ton scale for commercial launch.
