Procedure

Ciclesonide methanol solvate 100 gms (Form C) was suspended in 1.0 lt. of water and the suspension was stirred and heated at 50 to 60° C. for 2 hrs. The suspension was cooled to 25 to 30° C. The solid was filtered and washed with water and dried under vacuum at 90° C. for 6 hrs. to obtain 96 gms of anhydrous crystalline ciclesonide (Form A).
