実験手順

TEA (0.06 ml, 0.5 mmol) was added to a solution of methyl 2-(4-aminopiperidin-1-yl)-1,3-thiazole-5-carboxylate (Intermediate 134, 0.1 g, 0.5 mmol)) in anhydrous THF. To this was added 3,4-dichloro-5-cyano-1H-pyrrole-2-carbonyl chloride (Intermediate 132, 0.1 g, 0.5 mmol) as a solution in anhydrous THF. After stirring 15 minutes, THF was removed. The product was partitioned with EtOAc and water. The organic portion was dried with MgSO4 and concentrated to a yellow oil. Trituration with ether followed by filtration yielded a tan solid.
