2,4,6-Tri-tert-butylpyrimidine is the organic compound with the formula HC(Bu^tC)₂N₂C^tBu where ^tBu = (CH₃)₃C. It is a substituted derivative of the heterocycle pyrimidine. Known also as TTBP, this compound is of interest as a base that is sufficiently bulky to not bind boron trifluoride but still able to bind protons. It is less expensive that the related bulky derivatives of pyridine such as 2,6-di-tert-butylpyridine, 2,4,6-tri-tert-butylpyridine, and 2,6-di-tert-butyl-4-methylpyridine.^[1]
