Reaction Steps
In a manner similar to the method described in Example 379, chiral 2R,3S,4R,5S)-3-(3-chloro-2-fluoro-phenyl)-4-(4-chloro-2-fluoro-phenyl)-4-cyano-5-(2,2-dimethyl-propyl)-pyrrolidine-2-carboxylic acid (60.9 mg, 0.130 mmol) in N,N-dimethyl formamide (5 mL) were reacted with DIPEA (134 mg, 1.03 mmol), 5-(ethoxycarbonyl)pyridin-2-yl)methanaminium chloride (68.5 mg, 0.316 mmol, Chem-Impex), HOBt (34.0 mg, 0.252 mmol) and HBTU (93.5 mg, 0.247 mmol) at room temperature to give chiral 6-({[(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-carbonyl]-amino}-methyl)-nicotinic acid ethyl ester as a white solid, (81.3 mg, 99%). HRMS (ES+) m/z Calcd C32H32Cl2F2N4O3+H [(M+H): 629.1893. Found: 629.1896.
