반응 단계

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 (0.8 g, 1.7 mmol), N,N-diisopropylethylamine (663 mg, 5.1 mmol), 2-amino-N-(prop-2-yn-1-yl) acetamide hydrochloride (305 mg, 2.0 mmol) and HATU (974 g, 2.6 mmol) in CH2Cl2 (10 mL) at room temperature for 2 hours. The reaction mixture is diluted with CH2Cl2 (40 mL) and is washed with water (10 mL×3) and brine. Then the organic layer is dried over anhydrous Na2SO4 and 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-(prop-2-ynylamino)ethyl)-5,6-dihydro-4H-cyclopenta[c]thiophene-1-carboxamide as a white solid (850 mg, 88.4%). MS (m/z): 584.1 (M+Na).
