Procedure

4-Bromo aniline (0.25 g, 1.45 mmol), 2-pyrrolidin-1-ylpropanoic acid (0.25 g, 1.74 mmol) and diisopropylethylamine (0.3 ml, 1.74 mmol) were dissolved in dimethylacetamide (5 ml). HBTU (0.66 g, 1.74 mmol) was subsequently added and the mixture was stirred overnight. The reaction mixture was added to water and extracted twice with ethyl acetate. The combined organics were washed several times with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the desired product. Yield: 0.43 g, 100%. LCMS method: 2, RT: 2.73 min; MI: 297-299 [M+1].
