Reaction Steps

A single crystal X-ray diffraction study of racemic ilaprazole, Form F was done using crystals obtained from a acetone/methylene chloride solution. A solution of ilaprazole (˜35.8 mg) and piperazine (˜10.4 mg) was prepared in a solvent mixture of acetone (2.0 mL) and methylene chloride (0.5 mL) at room temperature. Hexanes (5.0 mL) were added to provide a turbid solution. The vial was sealed and the solution was left, undisturbed, at ambient conditions. Racemic ilaprazole, Form F crystals were observed after six days were subsampled from the parent sample.
