Procedure
To 1000 ml of ethanol was added 120 g of Lamivudine oxalate (prepared by the method of the present invention). 60 ml of triethylamine was added at the temperature of 40˜45° C. for 0.5 hour, stirred at the same temperature for 4 hours, and centrifuged at room temperature. The product was dried under vacuum at the temperature of 40˜45° C. to obtain Lamivudine crystal.
