Reaction Steps

Dissolve 3-[(m-fluorophenacyl)methylamino]-2-carbmethoxy-6-chloroindole (650 mg, 1.8 mmol) in tetrahydrofuran (10 mL) and water (10 mL). Add lithium hydroxide (227 mg, 5.4 mmol). Add methanol dropwise until an homogeneous solution forms. Stir the reaction at room temperature overnight. Dilute the reaction with water(10 mL) and ethyl acetate (25 mL). Acidify with 1N HCl and separate the layers. Dry the organic phase over magnesium sulfate, filter and concentrate 50% with heat. Reconstitute with hot hexane. Repeat the concentration and reconstitution steps and cool to yield the title compound (550 mg, 89%); mp 258°-260° C.
