Reaction Steps

A mixture of 484 mg (1.3 mmol) of 2-[[3-(2-amino-2-oxoethyl)-2-methyl-1-(phenylmethyl)-1H-indol-4-yl]oxy]acetic acid methyl ester (Example 39) and 2 mL of hydrazine in 10 mL of ethanol was heated to maintain reflux for 16 hours, 10 mL of ethanol added, heated an additional 4 hours and cooled. Ethyl acetate and water were added and the insoluble material filtered. The ethyl acetate solution was separated, washed with brine, dried (MgSO4) and concentrated. The residue was combined with he precipitate above co give 435 mg (91% yield) of 4-(2-hydrazino-2-oxoethoxy)-2-methyl-1-(phenylmethyl)-1H-indole-3-acetamide, mp, 207-210° C.
