Potassium Hydroxide → Potassium 4-[{[(4-fluorophenyl)methyl]imino}(hydroxy)methyl]-1-methyl-2-{2-[(5-methyl-1,3,4-oxadiazole-2-carbonyl)amino]propan-2-yl}-6-oxo-1,6-dihydropyrimidin-5-olate

Participants

Reaction Steps

A vial (20 ml) was charged with Raltegravir free hydroxy (0.5 g) and acetonitrile (7.5 mL) to obtain a solution. KOH 85% (75.6 mg) was added to the solution at room temperature. The solution was then sonicated for 40 minutes. The product was isolated by vacuum filtration to provide Raltegravir potassium Form X.
