Participants

Reaction Steps

To a stirred solution of isovaleric acid (0.025 mL in 4 mL methylene chloride) was added 1-hydroxybenzotriazole (37.8 mg) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (43.6 mg) and the reagents allowed to mix for 30 minutes. At this time a solution of {2-[2-(3,5-dimethylphenyl)-5-(N-hydroxycarbamimidoyl)-1H-indol-3-yl]ethyl}carbamic acid tert-butyl ester (81 mg in 3 mL methylene chloride) was added and the reaction stirred at room temperature. After 2 hours, the mixture was concentrated in vacuo and purified by flash chromatography on silica gel (methylene chloride:methanol, 96:4) to give the title compound (81 mg).
