実験手順

2-Chloro-5-phenyl-thiophene-3-carboxylic acid (28 mg, 0.11 mmol) was dissolved in DMF (1 mL). DIPEA (0.22 mmol), HATU (0.11 mmol) and pyrrolidine (0.11 mmol) were added and the reaction mixture stirred at room temperature. The reaction mixture was partitioned between ethyl acetate and 1 N hydrochloric acid. The organic solution was separated and dried over magnesium sulfate, filtered and the solvent evaporated. The residue was purified by preparative HPLC, eluting with 50%-90% acetonitrile in water (0.1% formic acid) over 30 minutes. The fractions containing the desired product were concentrated under vacuum to give the title compound (81 mg). LCMS m/z 292.10 [M+H]+ R.T.=11.27 mins (Analytical Method 1)
