Reaction Steps

A solution of 294 mg (1 mmol) of 4-hydroxy-2-methyl-1-(phenylmethyl)-1H-indole-3-acetamide was treated with 40 mg (1 mmol) of 60% NaH/mineral oil and after 1 hour, 0.15 mL (1 mmol) of ethyl 4-bromobutyrate was added. The mixture was stirred for 2 hours, diluted with water and extracted with EtOAc. The EtOAc solution was washed with NaCl solution, dried (MgSO4), and concentrated at reduced pressure. The residue was crystallized from MeOH/hexane to give a total of 235 mg (58% yield) of 4-[[3-(2-amino-2-oxoethyl)-2-methyl-1-(phenylmethyl)-1H-indol-4-yl]oxy]butanoic acid ethyl ester, mp, 115-116° C.
