Reaction Steps

The above benzoic acid (111 mg, 0.38 mmoles) was suspended in N,N-dimethylformamide (1 mL). 1-Hydroxybenzotriazole (55 mg, 0.42 mmoles), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (79 mg, 0.42 mmoles), and triethylamine (106 μL, 0.76 mmoles) were added and the resulting mixture was shaken at 1000 rpm for 1.5 hour. 4-(4-Chlorophenyl)-4,5,6,7-tetrahydro-thieno[3,2-c]pyridine (100 mg, 0.38 mmoles) was added and the resulting mixture was shaken at 1000 rpm for 3 hours. Water (2 mL) and ethyl acetate (1 mL) were added and the resulting mixture was shaken at 1000 rpm for 15 minutes, The organic phase was evaporated to afford 122 mg (66%) of the title compound as an oil.
