Patent ID: 8362260

Claim:
A process for preparing amorphous Dexlansoprazole comprising: drying Dexlansoprazole in crystalline form D having a water content ranging from about 3 to 8% w/w, an ethanol content ranging from about 4 to 8% w/w, having an XPRD wherein the most intense peaks fall at 6.7, 8.8, 12.2, 14.4, 17.9, 18.8, 19.2, 19.7, 20.2, 20.6 and 23.7±0.2° in 2θ, and having a DSC thermogram wherein the main endothermic peaks fall at about 65° C. and at about 145° C., at a temperature equal to or lower than 50° C., and recovering dried solid amorphous Dexlansoprazole.
