Procedure

Specifically, Lamivudine oxalate is added to ethanol, and an amount of triethylamine is added thereto at the temperature of 40˜45° C. for 0.5 hr, and stirred for 4 h at the same temperature. The mixture is centrifuged at room temperature, and a product is dried under vacuum at the temperature of 40˜45° C. to obtain Lamivudine crystal.

Workup

  1. customis centrifuged at room temperature
  2. customa product is dried under vacuum at the temperature of 40˜45° C.
