## Abstract Raman spectra of a 3‐methyl‐4‐nitropyridine __N__‐oxide crystal were investigated as a function of pressure in a diamond‐anvil cell up to 93 kbar at room temperature. The crystal shows successive reversible phase transitions at 8, 20 and 60 kbar. Above 60 kbar, all of the external Raman

## Abstract The nitro group of methyl 3‐nitropyridine‐4‐carboxylate (**1**) has successfully been replaced by nitrogen, oxygen and sulphur nucleophiles by nucleophilic aromatic substitution to give the 3‐azido, 3‐methoxy, 3‐phenoxy and 3‐thiophenoxypyridine‐4‐carboxylates (**2a — d**).
