実験手順

Methyl 6-cyano-7-(4-(3′,4′-dimethylbiphenyl-3-ylcarbamoyl)phenoxy)chroman-4-carboxylate (36 mg, 0.06759 mmol) was dissolved in THF (2 ml) and 1M solution of LiOH—H2O (135.2 μL, 0.135 mmol) was added. The mixture was stirred for 17 hours at ambient temperature. The mixture was quenched with 4M HCl dioxane (50.70 μL, 0.203 mmol). The crude mixture was purified on silica gel (MeOH in dichloromethane with 1% acetic acid gradient) to provide 31 mg of the title compound as a thin film (90%). MS (apci) m/z=519.1 (M+H).
