Procedure
Ivabradine (44 g) was dissolved in ethyl acetate (700 ml) and to this oxalic acid (22 g) in acetone (50 ml) was added slowly and stirred for 3-4 hours at ambient temperature. The ivabradine oxalate, thus obtained was filtered, washed with ethyl acetate (100 ml) and recrystallized in acetonitrile (350 ml). XRD pattern shows that isolated ivabradine oxalate was crystalline in nature and depicted in FIG. 2.
