Reaction Steps

In a 15 mL round-bottomed flask, (2R,3S,4R,5S)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxylic acid (250 mg, 535 μmol, Eq: 1.00), was combined with CH2Cl2 (3 ml) to give a clear solution. DIPEA (242 mg, 327 μl, 1.87 mmol, Eq: 3.5) and diphenylphosphenic chloride (316 mg, 255 μl, 1.34 mmol, Eq: 2.5) were added and the reaction was stirred at RT for 5 minutes. Methyl 4-amino-2-fluoro-5-methoxybenzoate (107 mg, 535 μmol, Eq: 1.00) was added and the reaction mixture was stirred at RT overnight.
