Reaction Steps

To (R)-2-[4-(3-amino-pyrrolidin-1-yl)-7-methyl-quinazolin-2-yl]-phenol (71 mg, 0.22 mmol) was added 890 μL of CH2Cl2. To this solution was added sequentially triethylamine (47 μL, 0.34 mmol) and 5-oxo-pyrrolidine-2-carboxylic acid (34.8 mg, 0.27 mmol) and BOP (119 mg, 0.27 mmol). The reaction mixture was stirred at room temperature for 2 h and diluted with water and CH2Cl2 (10 mL). The organic layer was separated and dried over Na2SO4, and the solvent was removed under reduced pressure to give (R)-5-oxo-pyrrolidine-2-carboxylic acid {1-[2-(2-hydroxy-phenyl)-7-methyl-quinazolin-4-yl]-pyrrolidin-3-yl}-amide. LC/MS: m/z 432.5 (M+H)+ at 2.24 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
