Procedure
5.4 gm of the metho sulfate of 2-chloro-9-methoxycarbonyl-10-methyl-acridinium were suspended in 50 cc of methanol and 2.5 cc of water and after the addition of 5 gm of potassium borohydride, the temperature maintained at 35°-40°C and the mixture was then stirred for 30 minutes at room temperature. The mixture was added to a mixture of ice and water and then filtered. The precipitate was washed with water and then iced mathanol and dried to obtain 3.45 gm of 2-chloro-9-methoxycarbonyl-10-methyl-acridane melting at 166°C. The product occurred as a colorless solid soluble in alcohol and chloroform, slightly soluble in ether and insoluble in water. For analysis, the product was recrystallized from methyl ethylketone.
