Reaction Steps

To a suspension of (S)-1,2-dimethyl-pyrrolidine-2-carboxylic acid (660 mg, 4.61 mmol), (5-fluoro-pyridin-2-yl)-hydrazine (488 mg, 3.84 mmol) and Et3N (1.1 mL, 7.7 mmol) in DCM (20 mL) were added HOBt.H2O (51 mg, 0.38 mmol) and EDCI.HCl (884 mg, 4.61 mmol) and the mixture stirred at RT overnight. The mixture was partitioned between EtOAc/water and extracted with EtOAc. The combined organics were dried (Na2SO4), filtered and concentrated in vacuo. FCC, using 0-10% MeOH in DCM, gave the title compound as a brown solid (668 mg, 69%). LCMS (Method 4): Rt 0.40, m/z 253 [MH+].
