Simple one step syntheses of indole-3-acetonitriles from indole-3-carboxaldehydes

One step conversion method of indole-3-carboxaldehydes into indole-3-acetonitriles is developed. Applying the method, 4-nitro- (7 a), 4-phenyl-(7 b), 4-iodo- (7 c), 4-methoxy- (7 d), and 4-benzyloxyindole-3-acetonitrile (7 e) are available in two steps from indole-3-carboxaldehyde (4).
