実験手順

A solution of 3-(5-fluoro-2-propoxy-phenyl)-propionic acid (160 mg, 0.71 mmoles) and benzoic acid N′-isopropyl-hydrazide (106 mg, 0.60 mmoles) in DMF (3 mL) was treated with diisopropylethylamine (0.26 mL, 1.49 mmoles), and PyBroP (416 mg, 0.89 mmoles) at room temperature for 16 h. The reaction mixture was partitioned between 1N HCl and ethyl acetate. The organic layer was washed successively with saturated aqueous sodium bicarbonate and brine, then dried over sodium sulfate, filtered and concentrated. The crude was absorbed on silica and purified on a silica gel column with a 20-50% ethyl acetate/hexanes gradient to afford the product as a solid (84 mg, 30%). LC-MS m/e 387.26 (M+H+)
