Procedure

To a stirred solution of 6-tert-butoxycarbonylamino-1-(2-chlorobenzyl)-3-isobutyryl-2-propylindole (581 mg) in ethyl acetate (5 ml) was added 4N hydrogen chloride in ethyl acetate (5 ml) at 20° C. The reaction mixture was stirred at 20° C. for 6.5 hours, then diluted with 1N aqueous sodium hydroxide and extracted. The organic phase was dried over magnesium sulfate and evaporated in vacuo. The residue was chromatographed on silica gel eluting with a mixture of ethyl acetate and hexane (1:6 to 1:4) to give 6-amino-1-(2-chlorobenzyl)-3-isobutyryl-2-propylindole (361 mg) as yellow oil.
