Procedure

Dissolve 3-[(phenacyl)methylamino]-2-carbmethoxy-6-chloroindole from above,in tetrahydrofuran (5 mL) and water (5 mL). Add lithium hydroxide and stir for 8 hours at 40° C. Dilute the reaction with water(10 mL) and ethyl acetate (10 mL). Separate the layers and acidify the aqueous layer. Extract the aqueous with ethyl acetate, dry the organic phase over magnesium sulfate, filter and concentrate in vacuo. Recrystallize from ethyl acetate/hexane to yield the title compound (75 mg); mp 250°-255° C.
