Canagliflozin (Invokana, JNJ-28431754) is an orally bioavailable and selective SGLT2 (subtype 2 sodium-glucose transport protein) inhibitor approved for the treatment of type 2 diabetes. Herein, we report the synthesis of 13 C and 14 C-labeled canagliflozin. Stable isotope-labeled [13 C6 ]canagliflozin was synthesized in 4 steps starting from [13 C6 ]-labeled glucose. The [14 C]-Labeled canagliflozin was synthesized by incorporation of [14 C] into the benzylic position between the thiophene and benzene rings of the compound. Detailed synthesis of the isotope-labeled compounds is reported.

Keywords: SGLT2 inhibitor; canagliflozin; isotope label; synthesis.
