Procedure

A flask (100 ml) was charged with Raltegravir free hydroxy (500 mg) completely dissolved in 1,4-dioxane (35 ml) at room temperature. A solution of 30% aqueous KOH (0.162 ml) was added. The resulting mixture was stirred for 24 h at room temperature. A solid precipitated and was filtered under reduced pressure to provide wet Raltegravir potassium crystalline Form VII.
