Abstract

Pantoprazole 1, SK & F 96022Z, an H^+^/K^+^ ATPase inhibitor has been prepared, radiolabelled with carbon‐14, in two positions, for drug metabolism studies. [Benzimidazole‐2‐^14^C]Pantoprazole in 4 steps from potassium ethyl [^14^C]xanthate, and [pyridylmethyl‐^14^C]pantoprazole from cuprous [^14^C]cyanide in 8 steps. The overall radiochemical yields of these syntheses were 37.9% and 5.2% respectively.
