Reaction Steps

To a solution of 2-(2,5-difluoro-4-{2-[(1S,2R)-2-piperidin-4 ylcyclopropyl]ethoxy}phenyl-)-N,N-dimethylacetamide (40.0 mg, 0.109 mmol) in 1 ml anhydrous dichloromethane at 0° C. was added triethylamine (0.0300 ml, 0.218 mmol) and 1-({[(1-methylcyclopropyl)oxy]carbonyl}oxy)pyrrolidine-2,5-dione (27.9 mg, 0.131 mmol). The reaction was stirred at RT for 2 hours. The solvent was evaporated, and the residue was purified by reverse-phase HPLC (SunFire Prep C18 OBD 5 um 19×100 mm column; 25-85% acetonitrile in 0.1% formic acid in water gradient) to give the title compound. LC/MS (m/z): 465.4 (M+H)+. Human EC50: 2.2 nM
