Procedure

Raltegravir (10 gm) was dissolved in dimethylformamide (100 ml) at room temperature and cooled to 10 to 15 deg C. To the reaction mass was added slowly a mixture of potassium hydroxide (1.5 gm) and water (2 ml) at 10 to 15 deg C. and the temperature was raised to 25 to 30 deg C., filtered. The solid obtained was washed with dimethylformamide and dried at 110 to 120 deg C. for 48 hours to obtain 7 gm of raltegravir potassium crystalline form H1.
