実験手順
To a solution of (S)-2-[1-(1,4-dimethyl-1H-indol-3-ylmethyl)-7-methoxy-2,4-dioxo-1,4-dihydro-2H-quinazolin-3-yl]-hexanoic acid methyl ester (145 mg, 0.30 mmol) in dioxane (2.5 ml) is added a solution of LiOH monohydrate (50 mg, 1.19 mmol) in H2O (2.5 mL). The resulting mixture is stirred at 60° C. for 4 hours. The reaction mixture is allowed to cool to room temperature, quenched with 4M HCl in dioxane (500 μL) and is concentrated. The resulting residue is triturated with H2O and MeOH to afford (S)-2-[1-(1,4-dimethyl-1H-indol-3-ylmethyl)-7-methoxy-2,4-dioxo-1,4-dihydro-2H-quinazolin-3-yl]-hexanoic acid. LCMS (ESMS): m/z 464.22 (M+H+).
