Procedure

1.66 kg of abexinostat (free base) are placed in 9.48 kg of a mixture of isopropanol/water (50/50 weight/weight) at ambient temperature. para-Toluenesulphonic acid monohydrate (0.83 kg) in 2.36 kg of water is added at ambient temperature. The mixture is then heated at 75° C. for 30 minutes before being cooled to 0° C. When crystallisation is complete, the suspension is filtered at 20° C. After drying, crystalline form I of abexinostat tosylate is obtained in a yield of about 85% and with a purity greater than 99%. The solid was characterised by the X-ray powder diffraction diagram, Raman spectrum and NMR spectrum as set out in Examples 3-5 and 6 hereinbelow.
