HCID 8028TetrahydrofuranSolvent

Procedure

Dissolve 3-amino-2-carbmethoxy-6-chloroindole (1 g, 4.4 mmol) in anhydrous tetrahydrofuran (50 mL). Add triethylamine (4.8 mmol) and acetylsalicoyl chloride (4.8 mmol) and stir for 5 minutes. Dilute into ethyl acetate (500 mL), separate the organic phase, wash with water, saturated sodium hydrogen carbonate and saturated sodium chloride. Dry and evaporate the solvent in vacuo. Recrystallize to give the title compound (1.3 g, 79%); mp 184°-86° C.
