Participants

Reaction Steps

To a solution of methyl 7-(4-(biphenyl-3-ylcarbamoyl)phenoxy)-6-cyanochroman-4-carboxylate (55.6 mg, 0.1102 mmol) in THF (2 ml) was added 1M solution of LiOH—H2O (220.4 μl, 0.2204 mmol). The mixture was stirred for 1 hour at ambient temperature. The mixture was quenched with 4M HCl dioxane (82.65 μl, 0.331 mmol). The crude mixture was purified on silica gel (MeOH in dichloromethane with 1% acetic acid gradient) to provide 40.4 mg of the title compound as a thin film (75%). MS (apci) m/z=491.1 (M+H).
