Procedure

To a solution of methyl 4-amino-6-chloro-4′-(dimethylamino)-[1,1′-biphenyl]-3-carboxylate (Intermediate 47) (10.8 g, 35.4 mmol) in dichloromethane (525 mL) was added 2-(3-methylisoxazol-5-yl)acetic acid (Aldrich, 5 g, 35.4 mmol), HATU (17.52 g, 46.1 mmol) and triethylamine (11.85 mL, 85 mmol) and the reaction mixture was stirred at room temperature for 72 h. The mixture was washed with water. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The residue was triturated with hot methanol, filtered and dried to give the title compound methyl 6-chloro-4′-(dimethylamino)-4-(2-(3-methylisoxazol-5-yl)acetamido)-[1,1′-biphenyl]-3-carboxylate (13.91 g, 32.5 mmol, 92% yield) as a beige solid. LCMS: (M+H)+=428; Rt=3.86 min.
