Procedure

To a vial charged with {1-[(5-chloro-2,4-dimethoxy-phenylcarbamoyl)-methyl]-2,4-dioxo-1,4-dihydro-2H-quinazolin-3-yl}-acetic acid (50.1 mg, 0.11 mmol), HATU (50.1 mg, 0.12 mmol), and (R)-pyrrolidin-3-yl-carbamic acid tert butyl ester (22.8 mg, 0.12 mmol), DMF (3 ml) was added. The stirring mixture is treated with DIPEA (33 μL, 0.275 mmol) and stirred at RT. Water is added to the mixture with stirring giving rise to a solid. This is filtered off and washed with water to afford the title compound; [M+H]+ 616
