Participants

Reaction Steps

2-Ethyl-4-hydroxy-1-(phenylmethyl)-1H-indole-3-acetamide (135 mg, 0.44 mmol) was added to 17.6 mg (0.44 mmol) of NaH/mineral oil (washed with hexanes) in 5 mL of DMF, stirred 1.5 hours, 0.04 mL (0.44 mmol) of methyl 2-bromoacetate added and stirring maintained for 3 hours. The mixture was diluted with water, extracted with ethyl acetate. The ethyl acetate was washed with brine, dried (MgSO4) and concentrated. The residue was chromatographed on silica gel eluting with 2% MeOH/ethyl acetate to give 34 mg (34% yield) of 2-[[3-(2-amino-2-oxoethyl)-1-(phenylmethyl)-1H-indol-4-yl]oxy]acetic acid methyl ester.
