Procedure

To a solution of rac-(2R,3S,4R,5S)—N-(4-(aminomethyl)phenyl)-3-(3-chloro-2-fluorophenyl)-4-(4-chloro-2-fluorophenyl)-4-cyano-5-neopentylpyrrolidine-2-carboxamide (21.0 mg, 0.0367 mmol, example XJ-2) in CH2Cl2 (4 ml) was treated with METHANESULFONYL CHLORIDE (8.5 mg, 5.78 μl, 0.0742 μmol) and the reaction was stirred at 0 C for 1 hr. The reaction mixture was diluted with CH2Cl2 (80 mL), washed with sat Na2CO3 (2×15 mL), water (2×15 mL) and evaporated. The crude material was purified by flash chromatography (silica gel, 4 g, 1% to 10% MeOH/CH2Cl2) to give rac-(2R,3S,4R,5S)-4-(4-Chloro-2-fluoro-phenyl)-3-(3-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid [4-(methanesulfonylamino-methyl)-phenyl]-amide as off-white solid (17.6 mg, 73%). MS (ES+) m/z Calcd: [(M+H)+]: 649. found: 649.
