反应详情

Crude 2-amino-4-(4-amino-phenyl)-thiophene-3-carboxylic acid amide (0.15 mmoles, 1 eq) is dissolved in 1 mL DMF and added to a solution of 2-fluoro-5-trifluoromethylbenzoic acid (0.20 mmoles, 1.3 equiv) and HBTU (0.20 mmoles, 1.3 equiv) in 1 mL DMF. To this solution is added 0.5 mL triethylamine. The solution is stirred at room temperature until the reaction is complete, as judged by TLC. The crude reaction mixture is purified by preparative HPLC, affording the desired 2-amino-4-{4-[(1-[2-fluoro-5-trifluoromethyl-phenyl]-methanoyl)-amino]-phenyl}-thiophene-3-carboxylic acid amide.
