Reaction Steps
DEAD (0.414 ml, 2.66 mmol) is slowly added to a solution of 4-Hydroxy-1H-indole-2-carboxylic acid methyl ester 75 (363 mg, 1.9 mmol), triphenylphosphine (698 mg, 2.66 mmol) and 2,2-Dimethyl-propan-1-ol (228 mg, 2.58 mmol) in 8 ml of THF. Stirring is continued for 20 hours and the solvent is then evaporated. The crude mixture is purified by chromatography on silicagel using cyclohexane/EtOAc (9/1).
