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 mg, 0.11 mmol), HATU (46.6 mg, 0.12 mmol), and dimethyl-(S)-pyrrolidin-3-yl-amine (14.0 mg, 0.12 mmol) DCM (2 ml) is added. The mixture is treated with DIPEA (48.6 μL, 2.79 mmol) and stirred at RT for 1 hour. DCM (5 ml) is added to the mixture and washed with 1M HCl. The acidic aqueous phase is treated with 1M NaOH until the pH is adjusted to pH of 7-8. The product is extracted from the aqueous phase with EtOAc (3×10 ml). The organic portions are combined, washed with water (10 ml), dried (MgSO4), filtered and concentrated to afford the title compound, [M+H]+ 544
