Reaction Steps

In 40 ml of dimethylformamide was suspended 2.84 g of sodium azide, and 10 g of 9-chloroacetylamino-1,2,3,4-tetrahydroacridine was added thereto and the mixture was reacted at room temperature for 2 hours. After addition of 32 ml of water to the mixture, precipitated crystals were filtered to give 9.7 g of 9-azidoacetylamino-1,2,3,4-tetrahydroacridine. Melting point: 190° C. (decomposed). These crystals were suspended in 500 ml of methanol, and hydrogenolysis was carried out by adding 0.5 g of palladium black at room temperature for one hour. After removal of the catalyst by filtration, the filtrate was condensed and recrystallized from methanol - isopropanol, and then filtered to give 7.4 g of the title compound. Melting point: 225° to 230° C.
