Versuchsvorschrift

Stir a mixture of 3-(5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)-5,6-dihydro-4H-cyclopenta[c]thiophene-1-carboxylic acid (1.0 g, 2.14 mmol), N,N-diisopropylethylamine (827 mg, 6.41 mmol), 2-amino-N-(2,2,2-trifluoroethyl) acetamide hydrochloride (658 mg, 2.56 mmol) and HATU (1.2 g, 3.2 mmol) in CH2Cl2 (10 mL) at room temperature for 2 hours. The reaction mixture is diluted with CH2Cl2 (50 mL) and is washed with water (10 mL×3) and brine. Then the organic layer is dried over anhydrous Na2SO4 and is concentrated under vacuum. Purify the residue by preparative HPLC to afford 3-(5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)-N-(2-oxo-2-(2,2,2-trifluoroethylamino)ethyl)-5,6-dihydro-4H-cyclopenta[c]thiophene-1-carboxamide as a white solid (1.1 g, 84.6%). MS (m/z): 606.0 (M+1).
