Ethyl 1-(4-chlorobenzyl)-1H-indole-2-carboxylate (2.00 g, 6.37 mmol) and lithium hydroxide (1.53 g, 63.7 mmol) were dissolved in THF:water (10 mL: 20 mL). The reaction was heated at 60° C. overnight. The reaction was cooled and further diluted with water. The reaction was transferred into a separatory funnel and was washed with diethyl ether. The aqueous layer was acidified using 2N HCl to pH 2 where a white solid formed. The suspension was returned to the separatory funnel and was washed with ethyl acetate. The organic layer was dried over magnesium sulfate, filtered and concentrated to obtain pure product as a white solid. Yield: 1.47 g, (White solid).
