4-Pyrrolidinylpyridine is an organic compound with the formula (CH2)4NC5H4N. The molecule consists of a pyrrodinyl group ((CH2)4N-) attached via N to the 4-position of pyridine. It is a white solid. The compound has attracted interest because it (pKa = 9.58) is more basic than dimethylaminopyridine (pKa = 9.41).[1] It is a popular base catalyst.[2]
