Isopropanol → methyl 4-(2-propoxy)-1H-indole-2-carboxylate

Participants

Reaction Steps

DEAD (0.227 ml, 1.47 mmol) is slowly added to a solution of 4-Hydroxy-1H-indole-2-carboxylic acid methyl ester 75 (200 mg, 1.05 mmol), triphenylphosphine (384 mg, 1.47 mmol) and isopropanol (0.108 ml, 1.43 mmol) in 2 ml of THF. Stirring is continued for 20 minutes and the solvent is then evaporated. The crude mixture is purified by chromatography on silicagel using cyclohexane/EtOAc (9/1).
