Procedure

Raltegravir (50 gm) was suspended in isopropyl alcohol (500 ml) and then added a solution of potassium hydroxide (8 gm) in water (10 ml) at 25 to 30° C. The reaction mass was stirred for 17 hours at 25 to 30° C. and filtered. The solid obtained was dried under vacuum at 60° C. for 9 hours to obtain 48 gm of raltegravir potassium crystalline form H1.
