実験手順

To a solution of 2-cyclopropyl-oxazole-4-carboxylic acid 1h (22.8 mg, 0.149 mmol) in DMF (5.0 mL) HATU (75.4 mg, 0.198 mmol) was added and stirred for 3 min. N, N-diisopropylethylamine (0.086 mL, 0.496 mmol) was added to this followed by 5-amino-2-fluoro-N-[3-(2-oxo-pyrrolidin-1-yl)-propyl]-4-(4-o-tolyl-piperazin-1-yl)-benzamide 3d (45.0 mg, 0.099 mmol) in DMF (2.0 mL) and the reaction was stirred at room temperature for 16 h. Saturated solution of lithium chloride was added to this and the contents were extracted with ethyl acetate dried on anhydrous sodium sulfate, concentrated and the crude 3e was dissolved in methanol and purified on preparative HPLC using water/methanol as eluent.
