Synthesis of 5-substituted indole derivatives. Part 3: A facile synthesis of 5-chloromethyl-1H-indole-2-carboxylates: Replacement of sulfonic acid functionality by chlorine

Pete, Béla,Toke, László

, p. 3373 - 3375 (2001)

Valuable new synthetic intermediates, 5-chloromethyl-1H-indole-2-carboxylates, were prepared by the elimination of SO2 from 2-ethoxycarbonyl-1H-indole-5-methanesulfonic acids, which are easily accessible by Fischer-type indolization.
