Reaction Steps
A 30 mL reaction vial is charged with 2-(5-bromo-2-cyclobutoxy-3-methyl-benzoylamino)-indan-2-carboxylic acid ethyl ester (0.29 g, 0.61 mmoles) is charged with 1,4-dioxane (4 mL) and MeOH (4 mL). A stirring bar is added and stirring is initiated. After dissolution, water (2 mL) is added followed by the LiOH monohydrate (65 mg, 1.55 mmol). After 38 h, tlc analysis (silica, 10% MeOH/DCM) indicates that the starting material is completely consumed. The pH of the reaction mixture is carefully adjusted to pH 2 by slowly adding dilute aqueous HCl (3%, ˜6 mL). The contents of the flask are poured into a separatory funnel which contains EtOAc (30 mL). The layers are separated. The aqueous layer is extracted with EtOAc (20 mL). The combined organic phases are washed with water (20 mL) and brine (20 mL), dried over MgSO4, filtered and concentrated by pumping to constant weight to give off white solid (0.26 g, 95%).
