title: A simple procedure for synthesis of roxindole, a dopamine D2-receptor agonist.
abstract: A modified convenient and high yielding synthetic route for the preparation of the dopamine agonist roxindole 1 is described. The key step in our method is the phase-transfer catalyzed reaction of gamma-butyrolactone with 5-methoxyindole which results in the indolylbutyric acid derivative directly in one step.
