Procedure
400 mg of sodium cyanoborohydride, 0.5 ml of 35% aqueous formaldehyde solution and a little sodium sulphate are added to a solution of 434 mg of 4-de-dimethylamino-4-amino-7-methoxy-6-thiatetracycline (obtained in accordance with Example 1) in 80 ml of methanol and the mixture is stirred for 30 minutes at 20°. Chloroform is then added, followed by washing with dilute hydrochloric acid, drying and evaporation to give 7-methoxy-6-thiatetracycline, m.p. 225°.
