Reaction Steps

5,6-Dihydro-5-oxo-4H-thieno[2,3-b]pyrrole-2-carboxamide (25 mg, 0.14 mmol) was dissolved in a solution of 1% piperidine in 2-propanol (2 ml). 3-(4-Methoxyphenyl)-1H-pyrazole-4-carboxaldehyde (0.15 mmol, 28 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 27 mg of (Z)-5,6-dihydro-5-oxo-4-[[3-(4-methoxyphenyl)-1H-pyrazol-4-yl]methylene]-4H-thieno [2,3-b]pyrrole-2-carboxamide as a brown solid. MS(ES): m/e 367 [M+H].
