実験手順
To a tetrahydrofuran/H2O/methanol (4 mL/1 mL/1 mL) solution of the methyl 2-methyl-2,3-dihydro-1H-indene-2-carboxylate (1.80 g, 9.46 mmol) was added lithium hydroxide monohydrate (1.19 g, 28.39 mmol). The reaction mixture stirred at ambient temperature for 4 hours and then the mixture was acidified to pH 3 using 1N HCl. The organics were extracted twice with 25 mL diethyl ether, the combined organics were washed with brine and then dried (Na2SO4), filtered and concentrated to as 2-Methyl-2,3-dihydro-1H-indene-2-carboxylic acid a white solid.
