Acetic Acid → 2,5-Di-pyridin-3-yl-pyrrol-1-ylamine

Participants

Reaction Steps

(2,5-di-pyridin-3-yl-pyrrol-1-yl)-carbamic acid 2-trimethylsilanyl-ethyl ester (1 g, 2.6 mmol) is treated with a 1M solution of TBAF in THF (5.2 ml, 5.2 mmol). The resulting solution is stirred overnight under Ar at rt, then quenched with glacial acetic acid (0.3 ml, 5.2 mmol) and diluted with toluene. The resulting solution is passed through a short plug of silica gel and concentrated in vacuo to afford 2,5-Di-pyridin-3-yl-pyrrol-1-ylamine.
