Reaction Steps

20 mg of lamotrigine was dissolved in 2 ml of methanol, 12 mg of malic acid sodium salt was added to the solution to form a single solution. The solution was then allowed to stand for several hours to effect the slow evaporation of solvent. The solids gathered were stored in screw cap vials for subsequent analysis.
