Reaction Steps

(R)-methyl 4-(1-(4,4-dimethyl-1-(4-(trifluoromethyl)benzyl)pyrrolidine-2-carboxamido)cyclopropyl)benzoate (D151) (100 mg, 0.21 mmol) was partitioned between dioxane (2 ml) and water (2 ml) prior addition of LiOH H2O (35 mg, 0.84 mmol) and the resulting mixture was stirred at RT for 18 hrs. Dioxane was evaporated off and the aqueous solution acidified with acetic acid to pH˜4-5. A white solid precipitated which was filtered, dried under vacuum, then re-dissolved in dioxane (2 ml) and water (2 ml) and hydrolysed for additional 5 hrs after addition of LiOH H2O (18 mg, 0.42 mmol). Dioxane was evaporated off and the aqueous solution acidified with acetic acid to pH˜4-5. A white solid precipitated which was filtered and dried under vacuum, to afford the title compound (E34) (35.5 mg).
