Reaction Steps

4-Dimethylaminobenzoic acid (0.20 g, 1.2 mmol) was dissolved in N,N-dimethylformamide (3 ml) and 1-hydroxybenzotriazole (0.20 g, 1.5 mmol) was added. To the resulting mixture N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.28 g, 1.5 mmol) was added and the mixture was stirred at room temperature for 15 minutes. 4-(4-Trifluoromethylphenyl)-4,5,6,7-tetrahydro-thieno[3,2-c]pyridine (0.41 g, 1.5 mmol) followed by diisopropylethylamine (0.42 ml, 2.4 mmol) were added and the mixture was stirred at room temperature for 16 hours. water (2 ml) was added and the mixture was extracted with ethyl acetate (2×5 ml). The combined organic extracts were washed with saturated aqueous sodium chloride solution (4 ml), dried (MgSO4) and concentrated in vacuo to afford the title compound.
