実験手順

Amine 47 (0.37 g) was dissolved in anhydrous DMF (5 mL). 1H-pyrrole-carboxylic acid (0.11 g), DIPEA (0.72 mL), EDC (0.25 g) and HOBt (0.2 g) were added and the reaction mixture was stirred at rt for 18 h before being partitioned between chloroform and 1M hydrochloric acid. The aqueous phase was extracted three more times with chloroform and the combined organic extracts were dried (MgSO4), filtered and concentrated in vacuo. Purification was achieved using flash chromatography, eluting with a gradient of 20% EtOAc/(50/70) petroleum ether to EtOAc to yield an off-white solid, 279 mg, 55%. Rf=0.15 (20% EtOAc/(50/70) petroleum ether).
