Abstract
1,159,626. Indole derivatives. MERCK & CO. Inc. 16 Aug., 1967 [25 Aug., 1966], No. 37645/67. Heading C2C. Indole derivatives of the general formula wherein R is a methoxy or dimethylamino group, are prepared by reduction of an indole derivative of the general formula conversion of the resulting novel indole derivative of the general formula to a corresponding diazonium salt, e.g. by means of dilute hydrochloric acid and aqueous sodium nitrite, followed by replacement of the diazonium group by a chlorine atom, e.g. by treatment with cuprous chloride, copper powder or copperbronze powder and hydrochloric acid.
