Reaction Steps

To the 2-(2-oxopyrrolidin-1-yl)acetic acid (186 mgs, 1.3 mmol) in DMF (3 mL), was added HATU (570 mg, 1.5 mmol), tert-butyl 3-(4-aminobenzamido)-4′-fluorobiphenyl-4-ylcarbamate (421 mg, 1.0 mmol) and NMM (0.3 mL, 3.0 mmol) and stirred at 55° C. for 40 hours. The reaction mixture was then diluted with water and acetonitrile and the precipitate was filtered, washed with water and dried and used further without purification. To the above BOC protected compound, 4.0 M HCl dioxane (7 mL) was added and stirred at room temperature for 2 hour. The reaction mixture was then diluted with ether and stirred. The resulting solid was filtered, washed with ether and dried to give the title compound.
