Reaction Steps
5,6-Dihydro-5-oxo-4H-thieno[2,3-b]pyrrole-2-carboxamide (30 mg, 0.17 mmol) was dissolved in a solution of 1% piperidine in 2-propanol (2 ml). 4-Methyl-5-imidazole carboxaldehyde (0.18 mmol, 15 mg) was added in one portion and the mixture heated at 75° C. for 1 hour. The reaction mixture was poured into an ice/water mixture (2 ml) and the precipitated solid was collected by filtration and washed with water to give 22 mg of (Z)-5,6-dihydro-4-[(3-methoxy-1H-pyrrol-2-yl)methylene]-5-oxo-4H-thieno[2,3-b]pyrrole-2-carboxamide as a yellow/brown solid. MS(ES): m/e 275 [M+H].
