Reaction Steps

To a solution of thietan-3-amine hydrobromide in N,N-dimethylformamide, triethylamine was added at 0° C. Then 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (122 mg, 0.53 mmol), 1-hydroxybenzotriazole monohydrate (72 mg, 0.53 mmol), and 2-methyl-4-[3-(3,4,5-trichlorophenyl)-3-(trifluoromethyl)-3,4-dihydro-2H-pyrrol-5-yl]benzoic acid (200 mg, 0.44 mmol) were added to the solution. The reaction mixture was stirred overnight at room temperature and then diluted with t-BuOMe and washed with 2M HCl, and after that with H2O, saturated NaCl aq. and dried over MgSO4. After evaporation, the residue was purified with chromatography (220 mg, 95%).
